You Searched For: Assays

An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, and molecular biology for qualitatively assessing or quantitatively measuring the presence or functional activity of the analyte, or the entity being targeted by the assay. Generally, assays involve biological materials or phenomena which tend to be intrinsically more complex in composition or in behavior than what can be handled by traditional chemical analysis and titration.

VWR® Bradford Method Protein Assay Kit

Supplier: VWR
Description: The Bradford Protein Assay is the preferred colorimetric assay for quantifying total protein concentration. Based upon complex formation between basic and aromatic amino acid residues with Coomassie® Brilliant Blue G-250 dye, the Bradford method is easier, faster, and more sensitive than the Lowry method. The standard protocol is used for measuring 10-100 μg of protein and the microassay is used for measuring 1-10 μg of protein. For maximum convenience, Bradford Reagent and 0.5 mg/ml BSA standard solution are offered individually or as components of a kit.

Crystal Digital PCR® Assay for BRAF (V600E, drop-off V600-K601)

Supplier: STILLA TECHNOLOGIES, INC.
Description: Assay-specific Crystal Flex Probes and primers for the detection of BRAF mutations and its Positive Control. BRAF (V600E, drop-off V600) Crystal Digital PCR® Assay is a 10X assay designed to detect and quantify mutations in codons V600-K601 plus 1 mutation in the BRAF gene. BRAF is pivotal in regulating cell signaling pathways implicated in cancer development, notably melanoma, colorectal cancer and thyroid cancer, through its role in the MAPK/ERK pathway. Mutations in BRAF, particularly the V600E mutation, lead to uncontrolled cell proliferation and survival.
