Emission spectra – Abcam Alexa Fluor<sup>®</sup> conjugated secondary antibodies
Alexa Fluor® 螢光發射光譜圖 (Emission chart) 。使用 Alexa Fluor® 螢光標定二級抗體進行多重染色實驗時,盡量避免選用發射光譜重疊的螢光染劑,以防實驗結果判讀不易、解析度下降。建議所選用的螢光染劑彼此間最大發射波長至少差距 40 nm 以上,例如:雙重染色時使用 Alexa Fluor® 488 搭配 Alexa Fluor® 647;三重染色時使用 Alexa Fluor® 405 搭配 Alexa Fluor® 555 與 Alexa Fluor® 647。

 

Abcam pre-adsorbed secondary antibodies
預吸附(交叉吸附)流程範例。將二抗溶液通過固定有血清蛋白(源自可能發生交叉反應的物種)的層析管柱。非專一性二抗將保留在管柱內,高專一性的二抗則會流出管柱。經由此純化步驟所獲得的預吸附二抗具有高度專一性,可降低交叉反應風險;然而經過預吸附處理的二抗可能對某些單抗的辨識能力較差,選擇時需特別謹慎。
