產(chǎn)品概述
脂聯(lián)素又被稱作Acrp30,AdipoQ,apM1,GBP28, Acrp30是一種分子量為30KD的脂肪細(xì)胞補(bǔ)體相關(guān)蛋白,基因轉(zhuǎn)錄物apM1是在脂肪組織中表達(dá)最豐富的轉(zhuǎn)錄物, GBP28是脂肪細(xì)胞特異性分泌的28KD凝膠蛋白,在維持機(jī)體葡萄糖和脂質(zhì)平衡上有著重要的作用,脂聯(lián)素結(jié)構(gòu)包括一個(gè)膠原樣區(qū)域組成的N-末端和球狀區(qū)域組成的C-末端,此區(qū)域有一段與補(bǔ)體因子C1q非常類似的序列,此外脂聯(lián)素還具有增加抗動(dòng)脈粥樣硬化和抗炎癥等生物學(xué)效應(yīng),在機(jī)體產(chǎn)生疾病時(shí)血漿中的脂聯(lián)素水平會(huì)降低。
產(chǎn)品原理
本實(shí)驗(yàn)采用雙抗體夾心ELISA法??谷薃diponectin單抗包被于酶標(biāo)板上,標(biāo)本和標(biāo)準(zhǔn)品中的Adiponectin會(huì)與單抗結(jié)合形成免疫復(fù)合物,游離的成分被洗去;加入生物素化的抗人Adiponectin抗體,生物素化抗人Adiponectin抗體與酶標(biāo)板上結(jié)合的標(biāo)準(zhǔn)品或樣本中的Adiponectin結(jié)合而形成免疫復(fù)合物,游離的成分被洗去;加入辣根過氧化物酶標(biāo)記的親合素,親合素與生物素特異性結(jié)合,游離的成分被洗去。加入顯色底物(顯色劑),若反應(yīng)孔中有Adiponectin,辣根過氧化物酶會(huì)使無(wú)色的顯色劑變藍(lán),加終止液變黃。在450nm處測(cè)OD值,Adiponectin濃度與OD450值之間呈正相關(guān),可通過繪制標(biāo)準(zhǔn)曲線求出標(biāo)本中Adiponectin濃度。
