黃麴毒素的分析;採用SPE-HPCL更快速 免疫親合管與SPE固相萃取管之操作步驟的比較
SPE幫你節省10倍的時間
前言
比免疫親合管再現性更好
傳統的黃麴毒素純化分析是採用免疫親和柱 IAC,需要採用”Binding and Wash”的機制,來濃縮和純化黃麴
霉毒素,純化後的樣品隨後用於分析。固相萃取管 (SPE),則是一種新的替代方法,利用“Interference
The following is an experiment comparing the use of the Supel
Removal”的方法達到樣品純化的目的,並且大大縮短樣品處理的時間。 Tox AflaZea SPE cartridge to a leading immunoaffinity column

比免疫親合管再現性更好
• 需要大量的液體製備 • 只需少量的液體製備
比免疫親合管節省10倍的時間 • 需要控制流速 • 需要抽氣裝置 Vacuum filtration
使用方式 • 需要較多的步驟 • 操驟步驟較少
方法與部驟非常簡單
• 需要配製鹽類緩衝液 • 不需要配製額外的緩衝鹽類
室溫保存; 效期比免疫親合管更久 • 需要冷藏保存 • SPE管室溫保存即可
