Bicinchoninic acid bca protein assay kit

Manufactured by Yeasen
Sourced in China

The Bicinchoninic acid (BCA) protein assay kit is a colorimetric detection and quantification method used to measure the total protein concentration in a sample. The kit utilizes the reaction between protein and an alkaline copper tartrate solution, which results in the reduction of Cu2+ to Cu+. The reduced copper then interacts with bicinchoninic acid, producing a purple-colored complex that can be measured spectrophotometrically.

Tissues and cells were lysed with RIPA buffer containing protease inhibitor (Bimake, #B14002) and phosphatase inhibitor (Bimake, #B15003). Bicinchoninic acid (BCA) protein assay kit (Yeasen, #20201ES90) was used to detect protein concentration. Equal quantity of proteins was separated by SDS‐PAGE and transferred to PVDF membrane. The membrane was blocked with 5% bovine serum albumin (Yeasen, #36101ES80) for 1–3 h at room temperature, and subsequently incubated with primary antibodies overnight at 4°C, followed by incubation with secondary antibodies for 1–3 h at room temperature. Next, the electrochemiluminescence reagents (Yeasen, #36208ES76) were used to detect the antibody signals, and quantitative analysis of the developed results was performed by ImageJ software using vinculin as an internal reference to calculate the relative expression levels of target protein. Primary antibodies of IMPA1(Abcam, #ab184165), Vinculin (Sigma, #V9131), and HA (CST, #3724S) were used in this study. Other antibody information is shown in Table S5.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
