ChromPure是我們來自非免疫動物血清的高純度蛋白質(zhì)的商品名。

物理狀態(tài)：冷凍干燥的固體
存儲：
儲存和再水化：將冷凍干燥的固體儲存在2-8°C。用體積的dH2O再水化，如果不清楚則離心。在使用當天準備工作稀釋液。產(chǎn)品在2-8℃下作為未稀釋的液體穩(wěn)定約6周。
再水化后的長期儲存：等分并在-70℃或更低溫度下冷凍。避免反復凍融?；蛘撸尤氲润w積的甘油（ACS級或更好），終濃度為50％，并在-20°C下儲存為液體。
失效日期：補液之日起一年。如果測試結(jié)果對于預(yù)期用途是可接受的，則可以延長失效日期。

Fluorescein (FITC)

Amax: 492 Emax: 520nm 

FITC (Fluorescein isothiocyanate) is the form of fluorescein used for conjugation to all of our antibodies and purified proteins, with the exception of streptavidin. Fluorescein conjugates absorb light maximally at 492 nm and fluoresce maximally at 520 nm. Although less bright than other green-fluorescing dyes, FITC is still a widely used fluorophore due to its long history. The major disadvantage of fluorescein is its rapid photobleaching (fading), which can be mitigated by the use of an anti-fading agent in the mounting medium. A better choice for many applications involving FITC is Alexa Fluor® 488 because it is brighter and more photostable.
