内收蛋白抗体产品介绍 Adducins are a family of cytoskeletal proteins encoded by three genes (alpha, beta, gamma). Adducin is a heterodimeric protein that consists of related subunits, which are produced from distinct genes but share a similar structure. Alpha and beta adducin include a protease-resistant N-terminal region and a protease-sensitive, hydrophilic C-terminal region. Alpha and gamma adducins are ubiquitously expressed. In contrast, beta adducin is expressed at high levels in brain and hematopoietic tissues. Adducin binds with high affinity to Ca2+/calmodulin and is a substrate for protein kinases A and C. Alternative splicing results in multiple variants encoding distinct isoforms; however, not all variants have been fully described.
Function : Membrane-cytoskeleton-associated protein that promotes the assembly of the spectrin-actin network. Binds to calmodulin. Calmodulin binds preferentially to the beta subunit.
Subunit : Heterodimer of an alpha and a beta subunit.
Subcellular Location : Cytoplasm, cytoskeleton. Cell membrane; Peripheral membrane protein; Cytoplasmic side.
Tissue Specificity : Expressed mainly in brain, spleen, kidney cortex and medulla, and heart. Also expressed in human umbilical vein endothelial cells, human vascular smooth muscle cells, kidney tubular cells and K-562 cell line.
Post-translational modifications : The N-terminus is blocked.
Similarity : Belongs to the aldolase class II family. Adducinbn subfamily.

内收蛋白(Adducin)是一种膜骨架蛋白,内收蛋白可与肌动蛋白及血影蛋白复合体结合,并且通过Ca2+和钙调蛋白的作用影响骨架蛋白的稳定性,从而影响红细胞的形态.
纯度:在实验的任何阶段,确定抗体溶液纯度的最简单方法是取一部分样本进行SDS-PAGE电泳。凝胶可用考马斯亮蓝染色(灵敏度为0.1—0.5ug/带)或银染(灵敏度1~l0ug/带)。
定量:如果抗体还不纯,有一个快捷的定量方法,即通过SDS-PAGE电泳分离出轻、重链,然后和已知的标准染色带比较。如果需要分析许多样本,用免疫测定法对抗体定量较容易。如果抗体是经过纯化的,可通过测蛋白总量代替上述两种方法,有一简单的方法,即紫外吸收法。内收蛋白抗体的量可通过测280nm处的吸收值来测(10D大致相当于0.75mg/m1的纯化抗体)。
抗原结合活性:一般说来,纯化方法不会引起抗原结合活性的改变。用蛋白G或蛋白A树脂很少导致抗体活性丧失。然而,如果最终抗体产物的作用不如原来所预料的好,检测抗体纯化过程所丢失的活性就极为重要。用一系列滴定法比较纯化的抗体和其原材料的活性,以标定每一步中的总抗体量,这将有助于较好的估计通过纯化所丢失的活性。
