NT-proBNP ELISA Kit (SK-1204)
背景簡介:
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NT-proBNP穩定性更好,檢測結果更可靠,是有效的心衰檢測工具。
產品優勢:
試劑盒特點:
檢測方法:夾心ELISA,HRP/TMB顯色
