WB, IHC
Human
N/A
IgG1
Storage Buffer & Condition: 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
1:3,000-1:100,00for ELLSA and Western blotting with chromogenic substrates
1:5,000-1:100,00 for Western blotting with ECL substates
The antibody reacts with whole molecule human IgG. It also reacts with the light chains of other human immunoglobulins.
Antibody Specificity: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、目的蛋白有多个修饰位点,本身可以呈现多条带,建议查阅文献或进行生物信息学分析,获得蛋白序列的修饰位点信息,通过去修饰确定蛋白实际大小;
2、样本处理过程中目的蛋白发生降解,建议加入蛋白酶抑制剂;样本处理时在冰上操作;
3、杂蛋白多,建议处理目的蛋白;
4、抗体特异性不强,建议使用特异性强的抗体;
5、抗体孵育时间过久,建议减少抗体孵育时间;
6、二抗与抗原有交叉反应,建议选择合适的封闭物;
7、二聚体或多聚体存在,建议增加蛋白质变性过程及强度;
8、底物显色与曝光时间过长,建议缩短显色及曝光的时间。
