Beta-Actin内参抗体

发表于由

内参即是内部参照（Internal Control），对于哺乳动物细胞表达来说一般是指由管家基因编码表达的蛋白，它们在各组织和细胞中的表达相对恒定，在检测蛋白的表达水平变化时常用它来做参照物。常用的蛋白质内参有细胞骨架蛋白beta-actin或beta-tubulin和GAPDH（glyceraldehyde-3-phosphate dehydrogenase）等。因此β-Actin抗体、β-Tubulin抗体以及GAPDH抗体成为最常见的三个动物细胞内参抗体。

Beta-Actin内参抗体其中Actin即肌动蛋白，是细胞的一种重要骨架蛋白。actin大致可分为六种，其中四种是不同肌肉组织特异性的，其余两种广泛分布于各种组织中，包括beta-actin和gamma-non-muscle actin。在肌肉组织中的beta-actin分布就很少，而心肌主要是alpha-cardiac muscle actin。

Beta-actin作为内参是得到了公认的，这是针对大多数组织和细胞来说的，它广泛分布于细胞浆内，表达量非常丰富。Beta-actin由375个氨基酸组成，分子量大小为42-43kDa左右。

针对β-Actin内参抗体，上海金畔生物科技有限公司有多种不同样式产品供您选择。上海金畔生物科技有限公司提供的所有内参抗体均为原装进口包装，且备有现货。上海金畔生物科技有限公司提供的所有优质内参，条带清晰，高效敏感，能为您提供最值得信赖的标签抗体产品保障和售后服务。

Bacterial[1]
体外研究
(In Vitro)

Expression of beta-defensin (pBD-1) mRNA increased from the proximal to the distal part of the intestine whereas pBD-2 expression decreased. The main gene expression sites for pBD-2 are kidney and liver, whereas pBD-1 is mainly expressed in tongue[1].
An eight-fold increase in pBD-1 mRNA expression is observed upon S. typhimurium infection in the porcine intestinal cell line IPEC J2[1].
Porcine beta-defensin 1 (pBD-1) also has immunomodulatory activity in porcine peripheral blood mononuclear cells and lymph node cells[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究
(In Vivo)

Resistance against respiratory infection with B. pertussis in older piglets is associated with the presence of Porcine beta-defensin 1 (pBD-1) in the upper respiratory tract. Furthermore, treatment with pBD-1 conferred complete protection of newborn piglets from intrapulmonary infection with B. pertussis[3].
