产品介绍:p21-activated kinases (PAKs) belong to the family of serine/threonine kinases involved in the control of various cellular processes, including the cell cycle, dynamics of the cytoskeleton, apoptosis, oncogenic transformation, and transcription. All PAK family members are characterized by the presence of p21-binding domain. p21-activated kinases are regulated by the small GTP-binding proteins Rac and Cdc42, and lipids, which stimulate autophosphorylation and phosphorylation of exogenous substrates. Serine (Ser-474) is the likely autophosphorylation site in the kinase domain of PAK4 in vivo. Phosphospecific antibodies directed against serine 474 detect activated PAK4 on the Golgi membrane when PAK4 is co-expressed with activated Cdc42. Current data strongly implicates PAK-4 in oncogenesis. PAK4 is frequently overexpressed in human tumor cell lines of various tissue origins.

Serine/threonine protein kinase that plays a role in a variety of different signaling pathways including cytoskeleton regulation, cell migration, growth, proliferation or cell survival. Activation by various effectors including growth factor receptors or active CDC42 and RAC1 results in a conformational change and a subsequent autophosphorylation on several serine and/or threonine residues. Phosphorylates and inactivates the protein phosphatase SSH1, leading to increased inhibitory phosphorylation of the actin binding/depolymerizing factor cofilin. Decreased cofilin activity may lead to stabilization of actin filaments. Phosphorylates LIMK1, a kinase that also inhibits the activity of cofilin. Phosphorylates integrin beta5/ITGB5 and thus regulates cell motility. Phosphorylates ARHGEF2 and activates the downstream target RHOA that plays a role in the regulation of assembly of focal adhesions and actin stress fibers. Stimulates cell survival by phosphorylating the BCL2 antagonist of cell death BAD. Alternatively, inhibits apoptosis by preventing caspase-8 binding to death domain receptors in a kinase independent manner. Plays a role in cell-cycle progression by controlling levels of the cell-cycle regulatory protein CDKN1A and by phosphorylating RAN.

免疫荧光技术的实验步骤：

一、准备好试剂与仪器：

磷酸盐缓冲盐水、荧光标记的抗体溶液、缓冲甘油、搪瓷桶三只、有盖搪瓷盒一只、荧光显微镜、玻片架、滤纸、37℃温箱等。

二、实验步骤

1.滴加0.01mol/L，pH7.4的PBS于待检标本片上，十分钟后弃去，使标本保持一定湿度。

2.滴加适当稀释的荧光标记的抗体溶液，使其覆盖标本，置于有盖搪瓷盒内，保温一定时间以三十分钟为参考。

3.取出玻片，置玻片架上，先用0.01mol/L，pH7.4的PBS冲洗后，再按顺序过0.01mol/L，pH7.4的PBS三缸浸泡，每缸三到五分钟，并不停地摇晃振荡。

4.取出玻片，用滤纸吸去多余水分，但不使标本干燥，加一滴缓冲甘油，以盖玻片覆盖。

5.立即用荧光显微镜观察。观察标本的特异性荧光强度。

抗体的定义：

抗体（antibody），（免疫球蛋白不仅仅只是抗体）是一种由浆细胞（效应B细胞）分泌，被免疫系统用来鉴别与中和外来物质如细菌、病毒等的大型Y形蛋白质，仅被发现存在于脊椎动物的血液等体液中，及其B细胞的细胞膜表面。抗体能识别特定外来物的一个特征，该外来目标被称为抗原。

动物抗体功能分类：

①猪抗体：猪瘟抗体，猪蓝耳抗体，猪圆环病毒抗体，猪伪狂犬抗体，猪细小病毒抗体，猪口蹄疫抗体，猪流感抗体等。

抗体的结构：

抗体是具有4条多肽链的对称结构，其中2条较长、相对分子量较大的相同的重链(H链)；2条较短、相对分子量较小的相同的轻链(L链)。链间由二硫键和非共价键联结形成一个由4条多肽链构成的单体分子。轻链有κ和λ两种，重链有μ、δ、γ、ε和α五种。 整个抗体分子可分为恒定区和可变区两部分。在给定的物种中，不同抗体分子的恒定区都具有相同的或几乎相同的氨基酸序列。可变区位于"Y"的两臂末端。在可变区内有一小部分氨基酸残基变化特别强烈，这些氨基酸的残基组成和排列顺序更易发生变异区域称高变区。高变区位于分子表面，最多由17个氨基酸残基构成，少则只有2 ～ 3个。高变区氨基酸序列决定了该抗体结合抗原抗原的特异性。一个抗体分子上的两个抗原结合部位是相同的，位于两臂末端称抗原结合片段(antigen-binding fragment, Fab)。"Y"的柄部称结晶片段(crystalline fragment,FC)，糖结合在FC 上。
