Limitations of bca assay
NettetBackground: The diagnostic value of microRNA (miRNA) detection in patients with bladder cancer (BCa) is controversial. We performed a diagnostic meta-analysis to evaluate current evidence on the use of miRNA assays to diagnose BCa. Methods: We systematically searched PubMed, Embase, and Web of Science for studies published … NettetBicinchoninic acid (BCA) assay or Smith assay is a copper-based colorimetric assay for total protein quantification. BCA rely on the formation of a Cu 2 + –protein complex in a …

NettetThe bicinchoninic acid (BCA) assay is one of many ways to measure the total protein concentration of an unknown sample. In this assay, copper (II) [Cu2+] is reduced to copper (I) [Cu1+] in the presence of peptides in alkaline solutions. BCA can chelate (bind to) Cu1+, creating a purple color with a maximum absorbance at 562 nm. As the protein ... NettetThe QuantiPro BCA Assay Kit is based on the same principals as the BCA1 Kit, except the QuantiPro BCA Kit gives a linear response from 0.5 to 30 µg/ml of protein, while the BCA1 Kit gives a linear response at higher concentrations of protein (200-1,000 µg/ml). Since the QuantiPro BCA assay can detect low
