Product Overview
| Description | Amino acid 32-327 of the Staphylococcus aureus subsp. aureus. The recombinant Protein A is a genetically engineered protein containing five Ig-binding regions of protein A and 6x His-tag on N-terminus. Cell wall binding region, albumin binding region and other non-specific binding regions have been eliminated from the recombinant Protein A to ensure the maximum specific IgG binding. The 6x His-tag on N-terminus can be used for affinity purification or for protein A detection using anti-His-tag antibody. The recombinant Protein A is ideal for purification of polyclonal or monoclonal IgG antibodies. Extinction Coefficient: 7450 (at 280nm) Specificity: Protein A binds to most human and mouse IgG subclasses (e.g., human IgG1, IgG2, IgG4; mouse IgG1, IgG2a, IgG2b, IgG3). It also binds to total IgG from bovine, guinea pig, hamster, equine, porcine and rabbit. Protein A has little affinity to chicken, goat, rat and sheep. Binding Capacity: ≥95% Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. |
