General description

Protein A is a 42 kDa bacterial protein. It is isolated from the cell wall of Staphylococcus aureus.
The fractionation procedure yields primarily the immunoglobulin fraction of antiserum. To ensure specificity the fractionated antiserum is adsorbed using solid phase techniques, if necessary. Rabbit Anti-Protein A is lyophilized from 0.01 M phosphate buffered saline, pH 7.2, to which no preservatives have been added. Identity and purity of the antibody is established by immunoelectrophoresis. Electrophoresis of the antibody preparation followed by diffusion versus anti-rabbit IgG results in a single arc of precipitation and versus anti-rabbit whole serum results in multiple arcs of precipitation.

Immunogen

Protein A from Staphylococcus aureus

Application

Anti-Protein A antibody produced in rabbit has been used in immunoblotting.
Protein A may be used as in immunoblotting with a minimum dilution of 1:50,000.

Biochem/physiol Actions

Protein A has an ability to bind Fc region of immunoglobulins from several species. It is used as a “universal tracer” and it facilitate the segregation of bound and free ligand. Protein A also acts as affinity matrices for antibody (IgG) purification.

Physical form

Lyophilized from 0.01M phosphate buffered saline, pH 7.2

Reconstitution

Reconstitute with 2 ml deionized water.

Most mitochondrial mRNAs in trypanosomatid parasites require uridine insertion/deletion RNA editing, a process mediated by guide RNA (gRNA) and catalyzed by multi-protein complexes called editosomes. The six oligonucleotide/oligosaccharide binding (OB)-fold proteins (KREPA1-A6), are a part of the common core of
