二抗也稱第二抗體，能和抗體結(jié)合，即抗體的抗體，其主要作用是檢測抗體的存在，放大一抗的信號，用于靶標(biāo)抗原的間接檢測。二抗帶有可以被檢測出的標(biāo)記（如帶熒光、放射性、化學(xué)發(fā)光或顯色基團(tuán)），可以和一抗結(jié)合，通過信號放大提高靈敏度，并為標(biāo)記和檢測提供了更大靈活性。可以說生物學(xué)研究、醫(yī)藥研究和開發(fā)都離不開好的二抗產(chǎn)品。
但令很多從事稀有物種研究的學(xué)者頭大的是——選擇一個物種對應(yīng)、質(zhì)量又好的二抗產(chǎn)品，真是太難了！猴、沙鼠、水貂、貓，要想生產(chǎn)這些罕見物種的二抗，并不是十分容易，因此鮮少有公司能提供全面的罕見物種靶標(biāo)二抗。
不過！看過小B這篇文章之后，一切問題都迎刃而解啦！提供品類豐富的高質(zhì)量標(biāo)記和未標(biāo)記二抗，涵蓋多種稀有罕見物種；可用于一抗的熒光、顯色和化學(xué)發(fā)光檢測，適合各種應(yīng)用，例如蛋白質(zhì)免疫印跡、免疫組化、流式細(xì)胞檢測和細(xì)胞成像。

| 產(chǎn)品介紹 | Immunoglobulin G (IgG), is one of the most abundant proteins in serum with normal levels between 8-17 mg/mL in adult blood. IgG is important for our defence against microorganisms and the molecules are produced by B lymphocytes as a part of our adaptive immune response. The IgG molecule has two separate functions; to bind to the pathogen that elicited the response and to recruit other cells and molecules to destroy the antigen. The variability of the IgG pool is generated by somatic recombination and the number of specificities in an individual at a given time point is estimated to be 1011 variants.
