WB, IHC
Mouse
N/A
IgG1
PBS, pH 7.4, 15mg/ml Bovine Serum Albumin as Stablizer and 50% Glycerol. Store at -20°C.
Do not aliquot the antibody.
1:500-1:5,000 for immunohisto/cytochemistry
1:5,000-1:100,000 for ELLSA and Western blotting with chromogenic substrates
1:10,000-1:200,000 for Western blotting with ECL substates
The antibody was purified from antisera by immunoaffinity chromatography using antigens coupled to agarose beads.
Based on immunoelectrophoresis and/or EL1SA,the antibody reacts with whole molecule mouse IgG. lt also reacts with the
light chains of other mouse immunoglobulins. No antibody was detected against non-immunoglobulin serum proteins.The
antibody may cross-react with immunoglobulins from other species.
Store at -20°C. Avoid repeated freeze / thaw cycles.The expiration date may be extended if test results are acceptable for the
intended use.
For in vitro research use only,not for diagnostic or therapeutic use.This product is not a medical device.

答:可能的原因有:
1、目的蛋白有多個修飾位點,本身可以呈現(xiàn)多條帶,建議查閱文獻(xiàn)或進(jìn)行生物信息學(xué)分析,獲得蛋白序列的修飾位點信息,通過去修飾確定蛋白實際大小;
2、樣本處理過程中目的蛋白發(fā)生降解,建議加入蛋白酶抑制劑;樣本處理時在冰上操作;
3、雜蛋白多,建議處理目的蛋白;
4、抗體特異性不強,建議使用特異性強的抗體;
5、抗體孵育時間過久,建議減少抗體孵育時間;
6、二抗與抗原有交叉反應(yīng),建議選擇合適的封閉物;
7、二聚體或多聚體存在,建議增加蛋白質(zhì)變性過程及強度;
8、底物顯色與曝光時間過長,建議縮短顯色及曝光的時間。
