β细胞素抗体产品介绍 Betacellulin (BTC), a member of the epidermal growth factor (EGF) family, was originally identified as a growth-promoting factor in the conditioned medium of a mouse pancreatic-cell carcinoma (insulinoma) cell line and has since been identified in humans. BTC is synthesized as a large transmembrane precursor molecule that can be cleaved proteolytically to release the soluble form of BTC or function as membrane-anchored growth factors in juxtacrine signaling. BTC, in addition to stimulating homodimers of ErbB-1 and ErbB-4, is capable of binding and activating all possible combinations of heterodimeric ErbB receptors including the oncogenic ErbB-2/ErbB-3 complex. BTC is also expressed in some human malignancies and may have an important role in tumor growth progression.
Function : Potent mitogen for retinal pigment epithelial cells and vascular smooth muscle cells. The effects of betacellulin are probably mediated by the EGF receptor and other related receptors.
Subunit : Monomer. Interacts with EGFR and ERBB4.
Subcellular Location : Cell membrane and Secreted > extracellular space.
Tissue Specificity : Synthesized in several tissues and tumor cells. Predominantly expressed in pancreas and small intestine.
Similarity : Contains 1 EGF-like domain.
Database links : UniProtKB/Swiss-Prot: P35070.1
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。β细胞素抗体的量可通过测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。
