Bcl2蛋白修饰因子抗体产品介绍 The BH3-only proteins, which include Blk, Bad, Bik, Hrk, BID, Bim, NOXA, PUMA and Bmf, are proapoptotic members of the Bcl-2 family. Bcl-2 modifying factor (Bmf) is a BH3-only protein that binds prosurvival Bcl-2 family members to initiate apoptosis. Bmf is sequestered to Myosin V motors on Actin in the cytoskeleton by associating with Dynein light chain 2 (DLC2) homodimers. If the cell undergoes loss of attachment (anoikis), the cytoskeleton is disrupted and Bmf is released from DLC2. Bmf then translocates to the mitochondria, where Bcl-2 (an anti-apoptotic family member) is sequestered. The BH3 domain of Bmf facilitates binding to a hydrophobic groove on the surface of Bcl-2. Binding results in a caspase cascade leading to apoptosis. Bmf is widely expressed in tissues such as pancreas, liver and kidney, and in hematopoietic tissues. The gene encoding Bmf maps to chromosome 15q14.
Function : May play a role in apoptosis. Isoform 1 seems to be the main initiator.
Subunit : Interacts with MCL1, BCL2, BCL2L1/BCL-Xl, BCL2A1 and BCL2L2/BCL-w. Interacts with the myosin V actin motor complex through its binding to DLC2
Tissue Specificity : Isoform 1 is mainly expressed in B-lymphoid cells. Isoform 2 and isoform 3 are mainly expressed in B-CLL and normal B-cells.
Similarity : Belongs to the Bcl-2 family.
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。Bcl2蛋白修饰因子抗体的量可通过测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。
