纯化的抗体可通过不同的途径获取,有些糖蛋白A33抗体可通过下述方法制备或从商家购买。从商家购买的抗体,通常附有正确的储存方法。
1)工作液应在4℃下融化并存放,可能稳定达数月。
2)如果没有特殊原因而避免使用叠氮钠,亦可加入叠氮钠,浓度为0.02%。将纯化的抗体样本分装成合适的体积,于-20℃保存。
3)纯化的抗体溶液应以较高的浓度(如lmg/m1)在中性pH下保存。:常用的抗体储存浓度高达l0mg/ml。较低浓度的抗体冻存前应浓缩。所有标准的浓缩方法(如超滤法),皆可使用。还有一个简单的方法是用蛋白A或蛋白G亲和柱来浓缩溶液。如果纯化的抗体不是用于标记,可将它们以较低浓度储存于加有1%BSA的溶液中。
4)经纯化制备的抗体在常用的缓冲液中是稳定的。其DH应保持在中性左右。如果pH在7-8之间,即使保存多年,对抗体也无损害。多数情况下,盐浓度适于保持在0-150mmol/L之间,但在长期存放的抗体中,盐溶液浓度高达500mmol/L时,对糖蛋白A33抗体能有损害。如果没有其他说明.律议用PBS或50mmol/LTris(DH8.0)溶液长期存放抗体。

糖蛋白A33抗体产品介绍 The glycoprotein encoded by this gene is a cell surface antigen that is expressed in greater than 95% of human colon cancers. The open reading frame encodes a 319 amino acid polypeptide having a putative secretory signal sequence and 3 potential glycosylation sites. The predicted mature protein has a 213 amino acid extracellular region, a single transmembrane domain, and a 62 amino acid intracellular tail. The sequence of the extracellular region contains 2 domains characteristic of the CD2 subgroup of the immunoglobulin (Ig) superfamily.
Function : May play a role in cell-cell recognition and signaling.
Subcellular Location : Membrane; Single-pass type I membrane protein.
Tissue Specificity : Expressed in normal gastrointestinal epithelium and in 95% of colon cancers.
Post-translational modifications : N-glycosylated, contains approximately 8 kDa of N-linked carbohydrate.
Palmitoylated.
Similarity : Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
Contains 1 Ig-like V-type (immunoglobulin-like) domain.
Database links : UniProtKB/Swiss-Prot: Q99795.1
