FAQs

Can I use PerfeCTa® SYBR® Green FastMix® instead of SYBR Green SuperMix?
You can use FastMix instead of SuperMix. We have observed similar results with both PCR mixes, however, slightly lower background was observed using SuperMix when using 10 ng of cDNA or more in the qPCR. The qScript microRNA Quantification system has been validated using SYBR Green SuperMix.
We use Perfecta Sybr Green Fastmix. We are starting to use uMELT software to predict qPCR melt curves. Could you please provide me with this info so that I can accurately use uMELT? [Mono+] : Concentration of monovalent cations in solution (mM).
The PerfeCta SYBR Green Fastmix has 50 mM salt and 2.2mM Free Mg at 1X. However, the co-solvents and the concentration of SYBR green I dye in the mastermix also affect amplicon Tm, so you may still not be able to accurately use uMELT. Our R&D has found uMELT mostly useful for predicting multiple melting domains in an amplicon.

Allelic variants of the aryl hydrocarbon receptor differentially influence UVB-mediated skin inflammatory responses in SKH1 mice
Kayla J. Smith, Toxicology - 2017
Abstract
The mouse strain SKH1 is widely used in skin research due to its hairless phenotype and intact immune system. Due to the complex nature of aryl hydrocarbon receptor (AHR) function in the skin, the development of additional in vivo models is necessary to study its role in cutaneous homeostasis and pathology. Variants of the Ah allele, exist among different mouse strains. The Ahb−1 and Ahd alleles express high and low affinity ligand binding forms of the AHR, respectively. The outbred SKH1 mice express the Ahb−2 and/or Ahd alleles. SKH1 mice were crossed with C57BL/6J mice, which harbor the Ahb−1 allele, to create useful models for studying endogenous AHR function. SKH1 mice were bred to be homozygous for either the Ahb−1 or Ahd allele to establish strains for use in comparative studies of the effects of differential ligand-mediated activation through gene expression changes upon UVB exposure. Ahb−1 or Ahd allelic status was confirmed by DNA sequence analysis. We tested the hypothesis that SKH1-Ahb−1 mice would display enhanced inflammatory signaling upon UVB exposure compared to SKH1-Ahd mice. Differential basal AHR activation between the strains was determined by assessing Cyp1a1 expression levels in the small intestine, liver, and skin of the SKH1-Ahb−1 mice compared to SKH1-Ahd mice. To determine whether SKH1-Ahb−1 mice are more prone to a pro-inflammatory phenotype in response to UVB, gene expression of inflammatory mediators was analyzed. SKH1-Ahb−1 mice expressed enhanced gene expression of the chemotactic factors Cxcl5, Cxcl1, and Ccl20, as well as the inflammatory signaling factors S100a9 and Ptgs2, compared to SKH1-Ahd mice in skin. These data supports a role for AHR activation and enhanced inflammatory signaling in skin.
Fine-scale spatial and temporal dynamics of kdr haplotypes in Aedes aegypti from Mexico
Marissa K. Grossman, BMC - 2019
Abstract
Background As resistance to insecticides increases in disease vectors, it has become exceedingly important to monitor populations for susceptibility. Most studies of field populations of Aedes aegypti have largely characterized resistance patterns at the spatial scale of the city or country, which may not be completely informative given that insecticide application occurs at the scale of the house or city block. Phenotypic resistance to pyrethroids dominates in Ae. aegypti, and it has been partially explained by mutations in the voltage-gated sodium channel gene. Here, we assess community-level patterns of four knockdown resistance (kdr) haplotypes (C1534/I1016, F1534/I1016, C1534/V1016 and F1534/V1016) in Ae. aegypti in 24 randomly chosen city blocks from a city in Yucatán State, Mexico, during both the dry and wet season and over two years. Results Three of the four haplotypes, C1534/I1016, C1534/V1016 and F1534/V1016 were heterogeneous between city blocks at all four sampling time points, and the double mutant haplotype, C1534/I1016, showed a significant increase following the wet season. The F1534/I1016 haplotype was rarely detected, similar to other studies. However, when haplotype frequencies were aggregated to a coarser spatial scale, the differences in space and time were obscured. Conclusions Our results provide empirical evidence that the selection of kdr alleles is occurring at fine spatial scales, indicating that future studies should include this scale to better understand evolutionary processes of resistance in natural populations.
Uptake and biological responses in land snail Cornu aspersum exposed to vaporized CdCl2
L. Sturba, Ecotoxicology and Environmental Safety - 2017
Abstract
The uptake of Cd and some biomarkers of exposure and effects have been investigated in specimens of land snail Cornu aspersum exposed to vaporized CdCl2 (10mg/L) for 7 days. The Cd levels quantified in snail's whole bodies confirmed Cd bioavailability trough vaporization and an higher accumulation in the midgut gland compared to the foot. Biological responses investigated showed a reduction of destabilization time of lysosomal membranes (NRRT) in hemocytes and an induction of catalase activities (CAT) in midgut gland. A further evidence of CdCl2 vaporized exposure was given by an increase in MT protein content as well as induction of Cd-MT gene expression, highlighting the central role of the midgut gland in Cd detoxification. These biomarkers can thus be considered as sensitive tools for the assessment of Cd contamination in the air using land snails as bioindicators. No changes in of GST activity and MDA were observed. From the overall results, the land snail, C. aspersum, could be used as good bioindicator of air quality for pollution monitoring purposes having shown clear signs of exposure and effects due Cd exposure by air.
Differentiation of the granulosa layer from hen prehierarchal follicles associated with follicle stimulating hormone receptor signaling
Dongwon Kim, Molecular Reproduction and Development - 2018
Abstract
Recruitment of a single follicle into the preovulatory hierarchy of the domestic hen ovary occurs from a small cohort of prehierarchal follicles measuring 6-8 mm in diameter. We have previously reported that granulosa cells (GC) collected from prehierarchal follicles express highest levels of membrane-localized follicle-stimulating hormone receptor (FSHR) during follicle development, yet fail to initiate signaling via cAMP following short-term incubation with FSH. Consequently, GC from prehierarchal follicles remain in an undifferentiated state and lack the capacity for steroidogenesis due to a deficiency of cAMP-dependent STAR protein and CYP11A1 gene expression. The present studies investigate FSH responsiveness in GC before and after the transition from undifferentiated to a differentiated state at follicle recruitment. Prior to recruitment focus is directed towards the inhibition of FSHR signaling by β-ARRESTIN (βARR). Specifically, knockdown of βARR mRNA in cultured, undifferentiated GC using small interfering RNA (siRNA) facilitated FSH-induced cAMP formation, STAR expression and progesterone production. Furthermore, over-expression of bovine βARR1 and G PROTEIN-COUPLED RECEPTOR KINASE2 in actively differentiating GC significantly decreased cAMP accumulation and progesterone production following a challenge with FSH. We propose that a βARR-mediated mechanism maintains FSHR unresponsiveness in undifferentiated GC from prehierarchal follicles, and as a result prevents GC differentiation until the time of follicle recruitment.

Increased Alternative Splicing as a Host Response to Edwardsiella ictaluri Infection in Catfish
Suxu Tan, Marine Biotechnology - 2018
Abstract
Alternative splicing is the process of generating multiple transcripts from a single pre-mRNA used by eukaryotes to regulate gene expression and increase proteomic complexity. Although alternative splicing profiles have been well studied in mammalian species, they have not been well studied in aquatic species, especially after biotic stresses. In the present study, genomic information and RNA-Seq datasets were utilized to characterize alternative splicing profiles and their induced changes after bacterial infection with Edwardsiella ictaluri in channel catfish (Ictalurus punctatus). A total of 27,476 alternative splicing events, derived from 9694 genes, were identified in channel catfish. Exon skipping was the most abundant while mutually exclusive exon was the least abundant type of alternative splicing. Alternative splicing was greatly induced by E. ictaluri infection with 21.9% increase in alternative splicing events. Interestingly, genes involved in RNA binding and RNA splicing themselves were significantly enriched in differentially alternatively spliced genes after infection. Sequence analyses of splice variants of a representative alternatively spliced gene, splicing factor srsf2, revealed that certain spliced transcripts may undergo nonsense-mediated decay (NMD), suggesting functional significance of the induced alternative splicing. Although statistical analysis was not possible with such large datasets, results from quantitative real-time PCR from representative differential alternative splicing events provided general validation of the bacterial infection-induced alternative splicing. This is the first comprehensive study of alternative splicing and its changes in response to bacterial infection in fish species, providing insights into the molecular mechanisms of host responses to biotic stresses.
