方法1:我們的抗體(凍干粉)已經(jīng)包含了0.01M PBS、1% BSA和0.1% 防腐劑(疊氮鈉或慶大霉素),您只需要加入滅菌的雙蒸水就行了。抗體溶解后,置于-20℃保存,最好分裝后使用,避免反復凍融,可保證至少1年有效;
方法2:也可以只加入一半體積的雙蒸水,再用一半體積的甘油補足,置于-20℃保存,這樣抗體不會凍,有利于抗體的穩(wěn)定。
后續(xù)試驗時,再使用對應的緩沖液稀釋成工作液,即用即配。
我們的抗體(凍干粉),在常溫放置下,至少一個月有效;若在-20℃下保存(推薦),至少三年有效。
Antibodies are prepared with 0.01M PBS, pH 7.4 with 1% BSA and 0.1% Sodium Azide, prior to lyophilization. Currently, we offer both lyophilized and reconstituted antibodies, both resulting in final concentration of 1mg/mL. We recommend two ways to reconstitute antibodies in lyophilized form:
1) Reconstituting by directly adding 100uL of sterile, distilled water.
2) Alternatively, if glycerol does not affect the experiment, add 50uL sterile distilled water, followed by adding 50uL of glycerol.
