Descrição geral
The use of recombinant Protein A in the production of Protein A agarose has the advantage that it is entirely free from Staphylococcal enterotoxins that are known to be mitogenic, and are contaminants in Protein A isolated from S. aureus. The immobilization chemistry provides high IgG-binding capacity and leak-proof stability under a wide range of pH and buffer conditions. The gel can be used over 30 times, depending on the elution condition.
Protein A leakage: <18 ng Protein A/ml (ELISA)
Regeneration: the gel can be used approximately 30 times
Structure: recombinant Protein A (E. coli, Mr = 45,000) is covalently coupled to crosslinked 6% agarose beads: 3 mg Protein A (>98% pure, HPLC, SDS-Page)/1 ml gel
Protein A, immobilized.

Especificidade
Protein A is a cell wall protein, isolated from a specific bacterial strain, which has specific binding sites for certain classes of immunoglobulins from different species. Protein A binds to varying degrees IgM, IgA, IgD, and most subclasses of IgG.
Aplicação
Purification of mouse monoclonal antibodies from ascites fluid or cell culture supernatants. Protein A or Protein G Agarose affinity matrix can be used to purify antibodies from crude cell extracts and for the immunoprecipitation or co-immunoprecipitation of proteins. It has also been used for photoactivatable-ribonucleoside-enhanced cross-linking immunoprecipitation (PAR-CLIP) analysis.
Componentes
Preswollen gel, ready-to-use, 2 ml or 5 ml gel (settled gel volume) in buffer that contains 20% ethanol as a preservative, nonsterile.
Protein A content: 3 mg/ml pre-swollen gel

Recently, we demonstrated that the microRNA 424(322)/503 [miR-424(322)/503] cluster is transcriptionally controlled by transforming growth factor β (TGF-β) in the mammary epithelium. Induction of this microRNA cluster impacts mammary epithelium fate by regulating apoptosis and insulin-like growth factor 1 (IGF1)

The accumulation of damaged or misfolded proteins, if unresolved, can lead to a detrimental consequence within cells termed proteotoxicity. Since cancerous cells often display elevated protein synthesis and by-product disposal, inhibition of the protein degradation pathways is an emerging approach
