Description générale

Protein A is a 42 kDa single chain polypeptide isolated from the cell wall of Staphylococcus aureus Cowan I strain.

Spécificité

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.

Immunogène

protein A from Cowan I strain of Staphy­lococcus aureus.

Application

Monoclonal Anti-Protein A antibody produced in mouse has been used in enzyme-linked immunosorbent assay (ELISA). It has also been used in western blot and dot blot analyses.

Actions biochimiques/physiologiques

Protein A is considered as a universal reagent in biochemistry and immunology, due to its affinity for the Fc region of many mammalian immunoglobulins. It is used for different applications such as purification of immunoglobulins by affinity chromatography, cell surface studies, radioimmunoassay (RIA), enzyme immunoassay (EIA), immunoprecipitations and many other procedures. It can be used in these methods either in its native form or conjugated to various markers.

Forme physique

Monoclonal Anti-Protein A antibody produced in mouse is provided as ascites fluid with 15 mM sodium azide.

Optimal glucose metabolism is central to the growth and development of cells. In microbial eukaryotes, carbon catabolite repression (CCR) mediates the preferential utilization of glucose, primarily by repressing alternate carbon source utilization. In fission yeast, CCR is mediated by transcriptional
