NT-proBNP ELISA Kit
為什么要檢測NT-proBNP ?
NT-proBNP是 proBNP分解后的76氨基酸片段。proBNP是心臟為彌補收縮無力而增大時,心壁被拉伸時由心臟釋放到血液中的化學物質。一旦從心臟釋放到血液中,proBNP就會分割為NT-proBNP和BNP。由于NT-proBNP的半衰期為120min,相比之下,BNP的半衰期僅20min。所以NT-proBNP可追蹤的時間可達24h而BNPzui多可監測的時間為1h。因此,檢測血清/血漿中的NT-proBNP穩定性更好,檢測結果更可靠,是有效的心衰檢測工具。

shen移植體液調節的標記物
用于流式或發光法檢測石蠟及冰凍切片C4d補體。
C4d是抗體觸發補體通過經典途徑活化后C4的裂解產物,能穩定地結合在發生排斥的移植物內皮的表面。檢測C4d作為機體針對同種異體移植物抗體檢測的一個間接信號,大量研究表明:C4d是shen移植免疫中的重要標記物,同時也是心臟、肝及其他器官移植免疫檢測的重要標記物。
檢測原理:
包被了HLA抗原的微球與被檢血清中的抗HLA抗體結合(A),形成抗原抗體復合物。加入補體后(血清取自健康非敏感人群),在微球表面激活了典型的補體級聯反應(B)。用
PE-conjugated anti human c4d 檢測結合的C4d。
產品優勢:
試劑盒特點:
1) 檢測樣本:血清
2) 來源:兔多克隆抗體
3) 形式:50ul,PE 標記純化的IgG片段。
4)應用:Luminex®-檢測、流式檢測
