Monoclonal Anti-Protein A-Biotin antibody produced in mouse

Monoclonal Anti-Protein A

基本信息
NACRES
NA.46
General description【一般描述】
Protein A is a cell wall associated protein isolated from Staphylococcus aureus Cowan 1 strain. The 42 kDa protein consists of a single polypeptide chain. Protein A possesses a specific affinity for Fc region of many mammalian immunoglobulins as human, rabbit, and guinea pig IgGs and therefore, considered as a universal reagent in biochemistry and immunology. Antibodies to protein A have been produced in rabbits, guinea pigs, chickens and mice. Protein A affinity chromatography has been achieved for the purification of immmunoglobulins. Monoclonal Anti-Protein A (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse.
Specificity【特异性】
Specific for Protein A and shows no cross-reactivity with Protein G. Reacts with free Protein A or IgG bound Protein A and does not interfere with the Fc binding activity of Protein A.
Immunogen【免疫原】
protein A from Cowan I strain of Staphy­lococcus aureus.
Application【应用】
Monoclonal Anti-Protein A-Biotin antibody produced in mouse may be used in ELISA at a working dilution of 1:80,000 - 1:160,000.
Biochem/physiol Actions【生化/生理作用】
Protein A is an immunoglobulin-binding protein present on the surface of Staphylococcus aureus and is also secreted into the extracellular environment. It binds the Fc region of Igs and Fab regions of B cell receptors. The coupling of biotin to monoclonal Anti-Protein A antibody allows for the binding of various labels such as avidin or streptavidin.
Physical form【外形】
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% inactivated bovine serum albumin and 15 mM sodium azide.
Preparation Note【制备说明】
Prepared by conjugation of biotinamidocaproate N-hydroxysuccinimide ester to fractionated monoclonal anti-Protein A.
