背景资料:
Avidin is a tetrameric protein of 4 identical subunits （homotetramer） each of which can bind to biotin with a high degrAvidin is a glycosylated polypeptide chain having a molecular mass of 68kDa and containg 4 subunits each with a binding site for biotin. The Avidin is purified by a鸡蛋白中提取纯化inity chromatographic techniques. The purification procedure ensures minimal contamination by other proteins or DNA. The resulting high activity and purity of the product gives very low non-specific binding （NSB）. of a鸡蛋白中提取纯化inity and specificity.

The Avidin is purified by a鸡蛋白中提取纯化inity chromatographic techniques. The purification procedure ensures minimal contamination by other proteins or DNA. The resulting high activity and purity of the product gives very low non-specific binding （NSB）.n 66-69 kDa. Avidin is produced in the oviducts of birds， reptiles and amphibians and is subsequently deposited in the whites of their es. In the chicken e white， avidin makes up roughly 0.05% of total protein （approximately 1.8 mg per e）. 10% of Avidin’s molecular weight is ascribed to carbohydrate content which is composed of four to five mannose and thrAvidin is a glycosylated polypeptide chain having a molecular mass of 68kDa and containg 4 subunits each with a binding site for biotin. The Avidin is purified by a鸡蛋白中提取纯化inity chromatographic techniques. The purification procedure ensures minimal contamination by other proteins or DNA. The resulting high activity and purity of the product gives very low non-specific binding （NSB）. N-acetylglucosamine residues.

The Avidin is purified by a鸡蛋白中提取纯化inity chromatographic techniques. The purification procedure ensures minimal contamination by other proteins or DNA. The resulting high activity and purity of the product gives very low non-specific binding （NSB）. 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.

溶解建议:
Sterile Filtered lyophilized powder. It is recommended to reconstitute the lyophilized Avidin in sterile 18MΩ-cm H2O not less than 100ug/ml or more than 10mg/ml solutions.

保存建议：
Avidin although stable at 4℃ for 3 weeks， should be stored desiccated below -18℃. For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）. Please prevent freeze-thaw cycles.
