There are several reasons for this, including the fact that the process for validating alternative assays
was still being developed.
The new offering developed by QIAGEN provides a very broad range of optimized and validated RNAi-based gene silencing solutions and, in addition, also links such RNAi solutions with the corresponding gene expression assay
used in the subsequent qPCR-based knockdown validation.
Neutralizing antibody titers are presented as geometric mean titers of assays
performed in triplicate.
The protein assay
kit consists of a protein extraction solution, test strips, reagent solutions for developing protein spot on the test strips, a card for estimating protein concentration by measuring the protein spot diameter and a simple-to-follow protocol.
After testing 73 chemicals, the researchers conclude that "no battery of tests constructed from these assays
improved substantially on the overall performance of the [Ames] .
Chapter 8 Fundamental principles of cell-based assays
To be recognized by the Fetal Medicine Foundation means that PerkinElmer has successfully demonstrated our common commitment to prenatal screening, and that our assays
meet their strict criteria to be used in FMF certified laboratories.
Because strong correlations between the data derived from ELISPOT, tetramer assays
, and intracellular cytokine staining for IFN-[gamma] were previously observed (14), vaccinia-specific T cells could be detected by flow cytometry only a few days after immunization with vaccinia virus.
Receptor binding assays
were conducted as per Van Dolah et al.
By combining DHI's expertise in viral antigen detection and specimen processing with our technologies, we expect to deliver highly sensitive, rapid assays
where there is currently a significant and unmet medical need.
anthracis isolates; 228 and 229 were positive by CW-DFA and CAP-DFA assays
We performed receptor binding assays
in 96-well plates in a buffer consisting of the following: 50 mM HEPES (pH 7.
DiscoveRx Corporation today announced that it has expanded its cell-based PathHunter(TM) [eth]-Arrestin assays
to include 45 validated cell products, each expressing a different Gi, Gs or Gq -coupled receptor.
In vitro methods for characterization of algal-derived toxins have relied largely upon functional assays
that include receptor-based assays
and cell-based toxicity assays
com/reports/c46516) has announced the addition of "Development of Cell-Based Assays
(Technical Insights)" to their offering.
