Leírás

Általános leírás

Staphylococcus aureus protein A, also known as SpA or IgG binding protein A, is a 42 kDa single chain polypeptide isolated from the cell wall of S. aureus Cowan I strain. It consists of a single polypeptide chain containing five repetitive immunoglobulin-binding domains, rich in aspartic and glutamic acids.Anti-Protein A antibody, Mouse monoclonal (mouse IgG1 isotype) is derived from the SPA-27 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from a BALB/c immunized mouse.

Egyediség

Monoclonal Anti-Protein A specifically recognizes Protein A from Staphylococcus aureus bacteria.

Immunogen

Protein A from Staphylococcus aureus Cowan I strain

Alkalmazás

The antibody may be used in various immunochemical techniques including immunoblotting, dot blot, ELISA, immunofluorescence, immunoprecipitation and flow cytometry (FACS).

Biokémiai/fiziológiai hatások

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 either in its native form, conjugated to various markers or serve as a tag for a specific protein of interest. In addition, protein A has low affinity to mouse monoclonal antibodies from IgG1 isotype. Thus, a monoclonal anti-protein A antibody of the mouse IgG1 isotype has an advantage due to its specific targeting and binding to protein A via its Fab fragment. Monoclonal anti-protein A antibody can serve a useful tool for quantification and visualization of S. aureus bacteria and bacterial contaminations in different examined samples and for detection of protein A tagged proteins.

Fizikai forma

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Tárolás és stabilitás

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
