What is the lowest copy number that can be used with the TaqMan Fast Universal PCR Master Mix (P/N 4352042)?
The fast master mix has demonstrated detection down to 10 copies of the RNase P gene with genomic DNA. Of course, detection limits may vary depending on factors such as assay design and sample preparation.
Which TaqMan assay types can be used when using the with TaqMan Fast Universal PCR Master Mix (P/N 4352042)?
The following research assays are supported using the TaqMan Fast Universal and/or Advanced Fast PCR Master Mix: TaqMan Gene Expression Assays, Custom TaqMan Gene Expression Assays, Custom primers and probes designed from Primer Express software-designed quantitative assays.
Are there any recommendations for running primer-limited VIC dye-labeled TaqMan Endogenous Controls using the Fast Universal PCR Master Mix such as Cat. No. 4352042?
For using primer-limited VIC dye-labeled TaqMan Endogenous Controls in a single-plex reaction, we recommend starting with an annealing/extension time of 30 sec and extension temperature of 62 ºC. For optimal performance, the recommendation is to use the TaqMan Fast Advanced Master Mix for such applications.
Are there any recommendations for running multiplex assays using the Fast Universal PCR Master Mix such as Cat. No. 4352042?
Multiplex assays applications are complex with variable performance results across different assays. Our recommendation is to use the TaqMan Fast Advanced Master Mix for such applications.
Can SNP assays be run using the TaqMan Fast Universal PCR Master Mix (Cat. No. 4352042)?
It may be technically feasible, but we have not fully validated TaqMan SNP Genotyping assays on the Applied Biosystems 7500 Fast System and therefore cannot recommend it.
Genetic analysis of hepatitis C virus with defective genome and its infectivity in vitro.

Journal:J Virol
PubMed ID:19369330
Replication and infectivity of hepatitis C virus (HCV) with a defective genome is ambiguous. We molecularly cloned 38 HCV isolates with defective genomes from 18 patient sera. The structural regions were widely deleted, with the 5' untranslated, core, and NS3-NS5B regions preserved. All of the deletions were in frame, ... More

'Background: The allochimeric MHC class I molecule [α1h1/u]-RT1. Aa that contains donor-type (Wistar Furth, WF; RT1u) epitopes displayed on recipient-type (ACI, RT1a) administered in conjunction with sub-therapeutic dose of cyclosporine (CsA) induces indefinite survival of heterotopic cardiac allografts in rat model. In vascularized transplantation models, the spleen contributes to graft ... More
Activation of Macrophages by Polysaccharide-protein Complex from Lycium barbarum L.
Authors:Chen, ZS; Soo, MY; Srinivasan, N; Tan, BKH; Chan, SH

PubMed ID:
'Macrophages play crucial roles in innate immunity. This paper reports that a polysaccharide-protein complex isolated from Lycium barbarum (LBP) is able to activate macrophages. LBP was isolated from Lycium barbarum fruit and separated to five homogenous fractions, designated LBPF1, LBPF2, LBPF3, LBPF4 and LBPF5. It was found that LBP (50 ... More
Fusion of Epstein-Barr virus nuclear antigen-1-derived glycine-alanine repeat to trans-dominant HIV-1 Gag increases inhibitory activities and survival of transduced cells in vivo
'Trans-dominant human immunodeficiency virus type 1 (HIV-1) Gag derivatives have been shown to efficiently inhibit late steps of HIV-1 replication in vitro by interfering with Gag precursor assembly, thus ranking among the interesting candidates for gene therapy approaches. However, efficient antiviral activities of corresponding transgenes are likely to be counteracted ... More
Prevalence of Chlamydophila psittaci in wild birds-potential risk for domestic poultry, pet birds, and public health?
Authors:Zweifel, D; Hoop, R; Sachse, K; Pospischil, A; Borel, N
Journal:
PubMed ID:
'To determine the prevalence of Chlamydophila psittaci in wild birds, cloacal swabs from 527 songbirds, 442 waterfowl, 84 feral pigeons, and 38 cormorants were examined by Chlamydiaceae-specific real-time polymerase chain reaction (PCR) and ArrayTube microarray assays for chlamydial species determination and genotyping of C. psittaci. Inconclusive cases were further characterized ... More
