Protein A Sepharose 4FF，Protein A Sepharose 4FF说明书
产品介绍
Protein A sepharose介质是经过我们公司长期开发，在公司生产的native protein A 的基础上精致而成。通过Protein A Sepharose 4FF，可分离和纯化多种哺乳动物不同亚型的抗体或包含抗体Fc片段的基因工程重组蛋白。
本产品相对同类产品具有如下优势：
1、偶联条件温和，更好的保持了protein A的构象，所以抗体载量高，同体积的介质，相同规模的纯化设备，相同体积介质，抗体的产量明显高于用同类产品，大大的降低了抗体药物生产成本。
2、非常稳定，不易脱落，用其生产的抗体中protein A的残留比同类产品的更少。
3、公司的Protein A 以及Protein A sepharose的生产都是在清洁车间生产，符合制药企业生产需求。

BPCa Bovine Activated Protein C
Activated Protein C （APC） is a serine protease derived from the two chain vitamin K dependent zymogen, Protein C. APC inhibits blood coagulation through the selective inactivation of the cofactors Va and VIIIa. APC is prepared from protein C by activation with purified thrombin. This thrombin is removed after activation by ion exchange chromatography. Activated Protein C purity is determined by SDS-PAGE and shows complete reduction upon incubation with 2-mercaptoethanol.
Buffer composition = 20 mM Tris-HCl/0.1 M NaCl /pH 7.4
Extinction Coefficient （1%） = 13.7
Molecular Weight = 52,650 daltons

BPC 1003 Bovine Protein C
Purified from fresh citrated bovine plasma using a combination of salt precipitations and column chromatography. Protein purity is determined by SDS-PAGE and shows total reduction upon incubation with 2-mercaptoethanol. Protein C is activated to the serine protease, Activated Protein C （APC）, by α-thrombin or the complex of α-thrombin/thrombomodulin. This APC is a potent anticoagulant through the selective inactivation of Factors Va and VIlla.

HPS Human Protein S
Protein S exists in two forms in human plasma, as the free protein and in complex with C4b-binding protein. Enzyme Research Laboratories offers the free protein from plasma which serves as a cofactor for the anticoagulant activity of activated protein C. Human protein S is a single-chain glycoprotein with a molecular weight of 69,000. HPS purity is determined by SDS-PAGE.
Buffer composition = 20 mM Tris-HCl/0.1 M NaCl /1 mM Benzamidine/pH 7.4
*Extinction Coefficient （1%） = 9.5
