纯化的抗体可通过不同的途径获取,有些胃泌素/蛙皮素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,对胃泌素/蛙皮素抗体能有损害。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。

胃泌素/蛙皮素抗体产品介绍 Gastrin is mainly known by its first described role as a gastric acid-hormone but the protein also has the ability to promote cellular growth. More recently, gastrin has been suggested to induce leukocyte-endothelial cell interactions and to have a pro-inflammatory effect. Gastrin has two biologically active peptide forms, G34 and G17 and they activate two different receptors: the CCK-1 receptor, which has low affinity for gastrin but high affinity for the related hormone cholecystokinin (CCK), and the CCK-2 receptor, which has high affinity for both gastrin and CCK and mediates the acid-secretory as well as the proliferative effects of gastrin.
Function : Gastrin stimulates the stomach mucosa to produce and secrete hydrochloric acid and the pancreas to secrete its digestive enzymes. It also stimulates smooth muscle contraction and increases blood circulation and water secretion in the stomach and intestine.
Subcellular Location : Secreted.
Post-translational modifications : Two different processing pathways probably exist in antral G-cells. In the dominant pathway progastrin is cleaved at three sites resulting in two major bioactive gastrins, gastrin-34 and gastrin-17. In the putative alternative pathway, progastrin may be processed only at the most C-terminal dibasic site resulting in the synthesis of gastrin-71.
Sulfation enhances proteolytic processing, and blocks peptide degradation. Levels of sulfation differ between proteolytically-cleaved gastrins. Thus, gastrin-6 is almost 73% sulfated, whereas the larger gastrins are less than 50% sulfated. Sulfation levels are also tissue-specific.
Similarity : Belongs to the gastrin/cholecystokinin family.

Gastrin又称蛙皮素(Bombesin),是一种含十七个氨基酸残基的多肽类激素。它是由胃黏膜产生,可刺激胃液、盐酸、及消化酶的分泌。Gastrin还可刺激平滑肌收缩、增加血液循环和胃肠道液体的分泌。
