產(chǎn)品簡介:
BCA蛋白濃度測定試劑盒(BCA Protein Assay Kit)是常用的兩種蛋白濃度檢測方法之一BCA法研制而成。BCA法的原理:在堿性條件下蛋白質(zhì)分子中肽鍵結(jié)構(gòu)與Cu2+絡(luò)合并將Cu2+還原成Cu1+。BCA特異地與Cu1+結(jié)合形成穩(wěn)定的藍(lán)紫色復(fù)合物,在562nm處有最大的光吸收值并于蛋白質(zhì)濃度成正比。該測定法實(shí)現(xiàn)了蛋白濃度測定的簡單,高穩(wěn)定性,高靈敏度和高兼容性。
BCA法測定蛋白濃度不受絕大部分樣品中的化學(xué)物質(zhì)的影響,可以兼容樣品中高達(dá)5%的SDS,5%的Triton X-100,5%的Tween 20,60,80。但受螯合劑和略高濃度的還原劑的影響,需確保EDTA低于10mM,無EGTA,二硫蘇糖醇低于1mM,β-巰基乙醇低于0.01%。不適用BCA法時建議試用GBCBIO Technologies生產(chǎn)的Bradford蛋白濃度測定試劑盒(G3722)。
產(chǎn)品特點(diǎn):
○靈敏度高,檢測濃度下限達(dá)到25μg/ml,檢測下限達(dá)到0.5μg
○在50-2000μg/ml濃度范圍內(nèi)有較好的線性關(guān)系
○受樣品中離子與去污劑的影響小
○可用酶標(biāo)儀或分光光度計(jì)進(jìn)行檢測
儲存和穩(wěn)定性:
BCA試劑A和B室溫保存,蛋白標(biāo)準(zhǔn)請-20℃凍存。本試劑盒自訂購之日起一年內(nèi)有效。
