| Description | |
| Avidin | |
| Accession (Primary) | P02701 |
| Synonyms | |
| Avidin, AVD, AVID. | |
| Introduction | |
| Avidin is a tetrameric protein of 4 identical subunits (homotetramer) which can bind to biotin with a high degree of affinity and specificity. The estimated molecular weight of Avidin in its tetrameric form is between 66-69 kDa. Avidin is produced in the oviducts of birds, reptiles and amphibians and is subsequently deposited in the whites of their eggs. In the chicken egg white, avidin makes up roughly 0.05% of total protein (approximately 1.8 mg per egg). 10% of Avidin’s molecular weight is ascribed to carbohydrate content which is composed of 4-5 mannose and 3 N-acetylglucosamine residues. Avidin has at least three distinctive oligosaccharide structural type which are similar in structure and composition. The dissociation constant (KD) of avidin is approximately 10-15M, making it one of the strongest known non-covalent bonds. | |
| Source | |
| Corn (Zea Mays). | |
| Physical Appearance | |
| Sterile Filtered white lyophilized powder. | |
| Stability | |
| Lyophilized Recombinant Avidin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Recombinant Avidin should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. | |
| Purity | |
| Greater than 90% as visualized by SDS-PAGE. | |
| Biological Activity | |
| 13.5 units/mg protein, 1 unit binds 1 µg biotin. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized Recombinant Avidin in sterile 18MΩ-cm H 2 O not less than 100 µg/ml or more than 10mg/ml solutions. | |
| Precautions | |
| Avidin Protein is for research use only and not for use in diagnostic or therapeutic procedures. | |
