Keyhole limpet hemocyanin is an extremely large, heterogeneous glycosylated protein consisting of subunits with a molecular weight of 350,000 and 390,000 in aggregates with molecular weights of 4,500,000-13,000,000. Each domain of a KLH subunit contains two copper atoms that together bind a single oxygen molecule (O2). When oxygen is bound to hemocyanin, the molecule takes on a distinctive transparent, opalescent blue color. The KLH protein is potently immunogenic yet safe in humans and is therefore highly prized as a vaccine carrier protein. The large and highly glycosylated KLH protein cannot be reproduced synthetically. It is available only as a purified biological product from the Keyhole Limpet Megathura crenulata. Keyhole limpet hemocyanin (KLH) is used extensively as a carrier protein in the production of antibodies for research, biotechnology and therapeutic applications. Haptens are substances with a low molecular weight such as peptides, small proteins and drug molecules that are generally not immunogenic and require the aid of a carrier protein to stimulate a response from the immune system in the form of antibody production. KLH is the most widely employed carrier proteins for this purpose. KLH is an effective carrier protein for several reasons. Its large size and numerous epitopes generate a substantial immune response, and abundance of lysine residues for coupling haptens, allows a high hapten:carrier protein ratio increasing the likelihood of generating hapten-specific antibodies. In addition, because KLH is derived from the limpet, a gastropod, it is phylogenetically distant from mammalian proteins, thus reducing false positives in immunologically based research techniques in mammalian model organisms. KLH may also be a challenging molecule to work with because of its propensity to aggregate and precipitate. Aggregates remain immunogenic, but limit the ability to conjugate haptens and are difficult to manipulate in the laboratory. A high quality KLH preparation with the clear opalescent blue color is the best indicator of KLH solubility. ?????????????????????????綠色熒光素（FITC）標(biāo)記標(biāo)記血藍(lán)蛋白 ?????????????????????????????產(chǎn) 品 說 明 ????熒光素標(biāo)記抗體（FA）是目前廣泛用于免疫病理、細(xì)胞化學(xué)、流氏細(xì)胞學(xué)、病理學(xué)及自身抗體的臨床免疫中的特異、靈敏、定性和定位相結(jié)合的免疫化學(xué)試劑。 ????我公司的熒光素抗體為本公司制備的抗血清，再經(jīng)過親和層析純化或特異性免疫親和層析純化的方法純化為抗體的IgG成分，并采用直接標(biāo)記法，將異硫氰酸熒光素（FITC美國sigma熒光素產(chǎn)品）共價(jià)交聯(lián)到抗體血管緊張素轉(zhuǎn)換酶（IgG）分子的賴氨酸分子上，經(jīng)過標(biāo)記偶聯(lián)、低溫透析、HPLC分離純化、分子篩過濾、濃縮管濃縮、蛋白定量、標(biāo)記后濃度鑒定、檢測、分裝、真空冷凍抽干而制備完成。 ????應(yīng)用范圍： ????1.免疫組織及免疫病理中抗原、抗體檢查，如：各腫瘤抗原檢查，細(xì)胞凋亡檢測。 ????2.用于細(xì)胞因子等檢查的熒光流式細(xì)胞儀測定。 ????3.用于臨床自身免疫病的多種自身抗體熒光檢查，如：抗核抗體，抗心肌酶抗體. ????4.白細(xì)胞分型抗原的免疫熒光染色。 ????5.用于細(xì)菌、病毒、梅毒螺旋體、鉤端螺旋體等微生物的抗原及抗體檢測。 ????主要性能： ????0.5ml或根據(jù)試驗(yàn)需求的各種包裝，并提供濃縮液或凍干粉，含有0.01%NaN3防腐劑。 ????血藍(lán)蛋白含量在1mg/1ml左右.FITC為Sigma異構(gòu)體I,約在70-80ug/ml,495nm為最大吸收峰，激發(fā)波長 525 nm . ????工作濃度： ????用0.01mol/l pH7.4 PBS 作1：20–1：50稀釋使用。 ????保存：-20°C可保存一年，避免反復(fù)凍融。 ????我公司可根據(jù)您科研的需求提供各種標(biāo)記服務(wù) ，標(biāo)記各種符合標(biāo)記條件的蛋白及抗體，質(zhì)量保證，用時(shí)短，價(jià)格合理。 |
