Bethyl Laboratories are making a lot of good antibodies. Usually its primary Ab can be used at 1:5000 to 1:20000. It is a lot cheaper per blot compared antibodies with 1:100 to 1:1000 dilutions from other big name companies. Another good thing for Bethyl is the company tests every marketed Ab for both IP and WB. The figures just come along with their products. This is really a good comercial practice. Next time if you screwed up by an antibody with no testing data shown, come to check if Bethyl have an Ab against your target of interest.
