| 詳細描述： |
轉鐵蛋白是血漿中主要的鐵傳遞蛋白，為細胞分化和細胞代謝提供所需的鐵。研究發(fā)現(xiàn) 所有的細胞生長都離不開轉鐵蛋白。不但維持正常的細胞代謝依賴于以生物活性形態(tài)存在的 鐵，鐵還是一些酶的輔助因子，比如 RNA 聚合酶，DNA 合成酶。同時也是血紅蛋白的重要 組成部分。
轉鐵蛋白是血漿糖蛋白，從血漿中分離而來，牛轉鐵蛋白以兩種分子形態(tài)存在，分子量 分別為 74KD 和 78KD。每個轉鐵蛋白分子通過 C 端和 N 端結構位點可以結合兩分子鐵離子， 所以轉鐵蛋白以三種形態(tài)存在：脫鐵（不結合鐵離子），飽和鐵（結合兩分子鐵離子）和部 分飽和，在生理情況下，轉鐵蛋白分子僅有 1/3 被鐵飽和。
使用說明： 轉鐵蛋白對于絕大部分細胞系在無血清培養(yǎng)基中生長是必需的，研究表明飽和鐵形態(tài)的 轉鐵蛋白對于促進細胞生長是最有效的形態(tài)。對于雜交瘤，黏連細胞和懸浮細胞系，在細胞 培養(yǎng)過程中，應保持培養(yǎng)基中轉鐵蛋白濃度在 0.5-100μ g/ml。針對不同的細胞系，需要選 擇最合適的濃度。
轉鐵蛋白凍干粉需要保存在冷藏狀態(tài)下，使用之前再溶解。一般用 PBS 或者其它合適 的溶劑在室溫下將轉鐵蛋白凍干粉溶解成儲液，濃度在 0.5-2.0mg/ml,然后用無菌濾膜進行過 濾，濾液可在無菌條件下 2-8℃保存 30 天。
