HaemoScan CH50 Test (Classical Pathway Complement Activity) 的詳細(xì)介紹

CH50 測試（經(jīng)典途徑補體活性）

經(jīng)典途徑方法（CH50）基于在 Ca++ 和 Mg++ 存在下裂解致敏綿羊紅細(xì)胞。
當(dāng)懷疑補體缺失或缺乏時，它可以作為篩查試驗。該測試對途徑成分的減少、缺失和惰性敏感。該方法也適用于評估醫(yī)藥產(chǎn)品對補體成分抑制或消耗的影響。

◆ 應(yīng)用
經(jīng)典途徑補體活性的測定
◆ 原理
將紅細(xì)胞懸液與連續(xù)稀釋的血清或血漿在 37 °C 下孵育 30 分鐘。
補體系統(tǒng)的活性導(dǎo)致溶血。孵育后，將樣品離心以獲得上清液。上清液中游離血紅蛋白的濃度與補體活性成正比，使用分光光度計在 415 nm 波長下測量。繪制血漿稀釋因子與溶血程度的關(guān)系可以計算 CH50。（即稀釋血清以獲得 50% 紅細(xì)胞的裂解）

該試劑盒旨在通過經(jīng)典途徑測量少量樣品（25 μL）中的補體活性，可在 96 孔（圓底）微孔板上執(zhí)行。該測定也可使用微量離心管進行。

◆ 保存和穩(wěn)定性
產(chǎn)品在 4°C 下可穩(wěn)定保存至少 6 周
