背景資料

Avidin is a tetrameric protein of 4 identical subunits （homotetramer） each of which can bind to biotin with a high degree of affinity and specificity. Avidin molecular weight in its tetrameric form is estimated to be 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 four to five mannose and three 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.

來源宿主

雞蛋白中提取純化

溶解建議

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.

保存建議

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.

其他

ProSpec 是一家全球著名細(xì)胞因子蛋白生產(chǎn)和研發(fā)的公司，具有20多年的生產(chǎn)經(jīng)驗，專注于蛋白（重組及合成）生產(chǎn)研發(fā)。我們的核心產(chǎn)品包括：干擾素、白介素、骨蛋白、腫瘤壞死因子、成纖維生長因子、瘦素、干細(xì)胞因子、催乳素、表皮生長因子、胰島素樣生長因子、神經(jīng)生長因子、集落刺激因子、激素、酶、病毒抗原以及各種重組蛋白等。 領(lǐng)先的生產(chǎn)工藝和規(guī)模使其可以提供毫克到克級蛋白，價格優(yōu)于同類公司。絕大部分產(chǎn)品是天然成熟型蛋白，而不含有標(biāo)簽蛋白。考慮到大部分研究者希望能更靈活地配制蛋白溶液，ProSpec-Tany絕大部分產(chǎn)品沒有添加保護(hù)劑或鹽，這就對工藝提出了更高的要求。同時，ProSpec-Tany絕大部分產(chǎn)品為凍干粉，因此易于運輸和保存。
