WesternBreeze™ 化学发光试剂盒，抗山羊

AP连接的山羊抗鼠和山羊抗兔二抗溶液可作为独立产品（货号WP20006和WP20007）购买，但是，AP连接的兔抗山羊二抗溶液不可作为独立产品购买。

可以，您可使用以下货号单独购买这些产品：

•货号WB7001（封闭液/稀释液A）
•货号WB7002（封闭液/稀释液B）
•货号WB7050（封闭液/稀释液A & B组合装）
•货号WB7003（抗体洗涤液）

可以，您可使用以下货号单独购买这些产品：

•化学发光底物，货号WP20002
•化学发光底物增强剂，货号WP20003

对于蛋白质免疫印迹，将蛋白质从SDS-PAGE凝胶转印到硝化纤维素或PVDF膜上后，立即使用20 mL纯水洗膜2次，每次5分钟，从而除去部分凝胶和转移缓冲液成分以及弱结合蛋白质。随后，膜可立即用于WesternBreeze化学发光免疫检测实验。
或者，将洗过的膜放在一张干净的滤纸上，在微热气流或红外灯下蒸干。适当干燥的膜可在4℃的密封容器内保存7天，保存时间取决于抗原。经水洗和干燥的硝化纤维素膜可立即用于WesternBreeze化学发光免疫检测实验方案。但是，经水洗和干燥的PVDF膜需要在甲醇中再润湿，随后用20 mL水洗涤2次，每次5分钟，最后用于WesternBreeze化学发光免疫检测实验。
对于非变性PAGE蛋白质免疫印迹，建议在所有洗涤步骤前实施干燥步骤，改善蛋白质与膜的结合。干燥后，应使用20 mL水将硝化纤维素膜洗涤2次，每次5分钟，然后再用于WesternBreeze化学发光免疫检测实验方案。干燥的PVDF膜需要在甲醇中再润湿，随后用20 mL水洗涤2次，每次5分钟，最后用于WesternBreeze化学发光免疫检测实验。

Western blotting is based on the separation of proteins by their size on a gel. However, migration of proteins through the gel matrix is also affected by other factors, which may cause the observed band size to be different from the predicted size.

Common causes are:
-Post-translational modification; for example phosphorylation and glycosylation increase the size of the protein
-Post-translation cleavage; many proteins are synthesized as precursor proteins, and then cleaved to give the active form
-Multimers, for example dimerization of a protein. This is usually prevented under reducing conditions, although strong interactions can result in the appearance of higher bands
-Splice variants; alternative splicing may result in different sized proteins being produced from the same gene
-Relative charge; the composition of amino acids (charged vs. non-charged)
