ACVR1B / ALK-4抗体
Antibody Type : Mouse Monoclonal Antibody ( Mouse mAb Service Platform )
克隆号 : 4E1C1F12
抗体宿主 : Mouse IgG1
缓冲液 : 0.2 μm filtered solution in PBS, 5% trehalose may be added in some batches. Please read the hardcopy of COA or contact our customer service to confirm the formulation.
制备方法 : This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, human cell-derived, recombinant human ALK4 extracellular domain ( rh ALK4 ; Catalog#10583-H08H ; NP_004293.1 ; Met 1 - Glu 126 ). The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.
ACVR1B / ALK-4抗体背景综述
Activin receptor type-IB, also known as Serine/threonine-protein kinase receptor R2, Activin receptor-like kinase 4, ALK-4, and ACVRIB, is a single-pass type I membrane protein which belongs to the protein kinase superfamily and TGFB receptor subfamily. Activins are dimeric growth and differentiation factors which belong to the transforming growth factor-beta (TGF-beta) superfamily of structurally related signaling proteins. Activins signal through a heteromeric complex of receptor serine kinases which include at least two type I (I and IB) and two type II (II and IIB) receptors. These receptors are all transmembrane proteins, composed of a ligand-binding extracellular domain with a cysteine-rich region, a transmembrane domain, and a cytoplasmic domain with predicted serine/threonine specificity. ALK-4 is expressed in many tissues, most strongly in kidney, pancreas, brain, lung, and liver. ALK4 and ALK7 can mediate signal transduction by Nodal proteins, although ALK7 appears to be a receptor more specifically dedicated to Nodal signaling.

文献和实验脾细胞与小鼠骨髓瘤细胞(P3-X63/Ag8)融合,融合的细胞既获得了亲代脾细胞分泌特异性抗体的特性,又具有骨髓瘤细胞大量繁殖的能力,成为一种既能分泌特异性抗体又能长命的杂交瘤细胞。该技术为抗体的分子生物学研究提供了全新的手段。极大地促进了免疫学,遗传学,分子生物学的快速发展。 但传统抗体目前也面临诸多问题,如: 每使用一管新抗体都需要进行滴定测试; 多种同型对照,实验设计繁琐; 需要添加Fc阻断试剂; 抗体不佳,阳性细胞群不明显; 抗体作为细胞生物学和生物化学中最重要的试剂之一,科学界每年在这类

luozhifeng339 请教各位达达,我准备做EMSA,如果做SUPER-SHIFT的话,该选择原装抗体还是分装的抗体呢,盼不吝赐教! wanglinling 看到一篇EMSA的文章,不知道里面有没有回答你的问题哈,不过英文的值得阅读哈。 GEL SUPER-SHIFT ASSAY/ EMSA Materials/Reagents: See Gel-shift assay Procedure
