Protein a ap secondary antibody

Manufactured by Merck Group

Protein A-AP secondary antibody is a laboratory reagent used in various immunoassays and immunochemical techniques. It is composed of Protein A, a bacterial protein that binds to the Fc region of immunoglobulins, coupled to alkaline phosphatase (AP), an enzyme that catalyzes a color-producing reaction. This secondary antibody can be used to detect and quantify the presence of primary antibodies in a sample.

Each of the OMP preparations (5 μg) were run on the Novex Bis-Tris pre-cast gel system with MOPS running buffer according to the manufacturer's instructions (Life Technologies). Ammoniacal silver staining was carried out to visualize proteins. Western blotting was carried out using nitro-cellulose membranes (Bio-Rad) and standard protocols68 . All mouse (AD6 anti-HMW1/2A34 (link); 1F4 anti-Hia35 (link)) and rabbit (LB1 anti-OMP P5 (ref. 28 (link)); chimV4 anti-OMP P5; anti-OMP P5) primary antibodies were used at a dilution of 1:2,500; all chinchilla (anti-OMP P2; anti-LPD27 (link); anti-PDM27 (link); anti-OMP P5/P6) primary antibodies at a dilution of 1:250. Anti-mouse-AP and anti-rabbit-AP secondary antibodies were used at a dilution of 1:5,000 (Sigma-Aldrich); protein A-AP secondary antibody was used at a dilution of 1:500 (Sigma-Aldrich) in blots where chinchilla primary antibodies were used. Blots were developed using SigmaFAST NBT/BCIP tablets according to the manufacturer's instructions (Sigma-Aldrich). All the primary antibodies were raised by the authors laboratories, with specific references for those described previously.

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.
