CHO宿主細胞蛋白酶聯免疫試劑盒 | 貨號E4537-100
CHO Host Cell Proteins Elisa kit
產品介紹: CHO細胞株(CHO cell line)廣泛用於治療性蛋白(therapeutic protein)的表達,這是一種經濟有效的方法,用於生產商業數量的原料藥()。設計生物製藥產品(biopharmaceutical products)下游工藝的目標之一是去除任何可能的污染物(contaminants),包括宿主細胞蛋白(host cell proteins)。在經過幾個純化(purification)步驟後,HCP仍會以很高的濃度存在,甚至可以與原料藥本身一起純化(co-purified)和濃縮(concentrated)。產品中的HCP會導致不良的毒性(toxic)或免疫反應(immunological reactions),從而損害產品的安全性和質量。希望將宿主細胞蛋白質(host cell protein)污染降低到最低水平。因此,在下游過程的開發過程中,必須有合適的測定方法來確定存在的HCP量。BioVision的CHO HCP ELISA試劑盒是一種夾心ELISA測定法,用於定量測定人血清,血漿和細胞培養上清液中的CHO HCP 。顏色的密度與從樣品中捕獲的CHO HCP的量成正比。
