Anti-Integrin alpha 1抗體,整合素α1抗體產(chǎn)品介紹:Integrins are important extracellular matrix (ECM) receptor proteins located on cell surfaces. They are hetrodimers composed of an alpha and a beta transmembrane glycoprotein subunit. Around twenty two different integrins (different alpha/ beta subunit combinations) are found in nature. Integrins are generally present in high concentrations at the cell surface, but, unlike most other cell surface receptors, they bind ligands with very low affinity. Due to their weak individual binding, integrins need to cluster and bind in groups in order to effectively bind the ECM. Integrins bind many different ligands including laminin. Each integrin is made up of a large N terminal extracellular domain that binds the ECM ligand and a small C terminal cytoplasmic domain that mediates interaction with the actin cytoskeleton and signaling function. Alpha 1 integrin along with alpha 2, alpha L and alpha M has a unique inserted domain. Integrin alpha 1 is a receptor for laminin and collagen. The alpha1 subunit is also known as CD49a. CD49a associates with CD29 (beta 1 integrin), to form an alpha1 beta1 heterodimer, identified as the rat homologue to VLA1, which is involved in cellular adhesion to laminin and collagen.
保存條件:Store at -20 °C for one year. Avoid repeated freeze/thaw cycles. The lyophilized antibody is stable at room temperature for at least one month and for greater than a year when kept at -20°C. When reconstituted in sterile pH 7.4 0.01M PBS or diluent of antibody the antibody is stable for at least two weeks at 2-4 °C.避免反復(fù)凍融,保質(zhì)期一年。
上海研盟生物科技有限公司多抗親和層析純化
多抗的純化是一件比較簡單的事情,因?yàn)槿斯じ深A(yù)比較大,所以對(duì)實(shí)驗(yàn)者的操作依賴性較強(qiáng)。很多新手覺得這是一件比較復(fù)雜困難的工作,但是如果理解了原理,就可以自行改進(jìn)實(shí)驗(yàn)了。多抗純化方法比較多,過去有用鹽析法純化的,有用辛酸-硫酸銨沉淀的方式純化的,也有用冷酒精沉淀的方式純化的,也有后來的離子交換層析和Protein A、G、A/G 純化的,但是在今天,市場上幾乎所有的抗體都是通過抗原親和純化得到的,與其它方法相比,抗原親和層析得到的抗體效率高、產(chǎn)量高、產(chǎn)品純、操作簡單。鑒于很多網(wǎng)友問起這方面的問題,我就詳細(xì)地講一講親和純化原理和操作。
說到親和層析,還得從上個(gè)世紀(jì)60年代說起。當(dāng)年美國NIH(National Institutes of Health)
有個(gè)學(xué)生在研究一種酶和抑制劑之間的相互作用的時(shí)候,突發(fā)奇想:既然此酶可以和抑制劑結(jié)合,那如果把抑制劑固定起來,不就可以用來純化酶了嗎?試了一下覺得果然可行于是發(fā)了論文,從那之后,就出現(xiàn)了各種各樣的親和層析,親和配基與配體可以是酶與底物、酶與抑制劑、激素與受體、抗原和抗體、糖蛋白與凝集素、*與親和素、*與二價(jià)金屬離子、卟啉環(huán)與亞鐵離子等。親和層析精髓:將一種分子固定,用來吸附另一種特異性分子,zui后將其洗脫下來。
