설명

일반 설명

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.

특이성

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.

면역원

protein A from Cowan I strain of Staphy­lococcus aureus.

애플리케이션

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.

생화학적/생리학적 작용

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.

물리적 형태

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% inactivated bovine serum albumin and 15 mM sodium azide.

제조 메모

Prepared by conjugation of biotinamidocaproate N-hydroxysuccinimide ester to fractionated monoclonal anti-Protein A.

저장 및 안정성

Store at 2-8 °C for up to one month. For extended storage, solution may be frozen in working aliquots. Repeated freezing and thawing, or storage in "frostfree" freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify by centrifugation before use.
