Descripción general
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.

Especificidad
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.
Aplicación
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

Over the last decade, it has been noticed that microbial pathogens and pests deliver small RNA (sRNA) effectors into their host plants to manipulate plant physiology and immunity for infection, known as cross kingdom RNA interference. In this process, fungal

Through the canonical LC3 interaction motif (LIR), [W/F/Y]-X1-X2-[I/L/V], protein complexes are recruited to autophagosomes to perform their functions as either autophagy adaptors or receptors. How these adaptors/receptors selectively interact with either LC3 or GABARAP families remains unclear. Herein, we determine

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)
