Go to datasheet (ab5831)


Could you please send me a few more experimental details for our records:

1) What samples and species was used? Human fibroblasts.
2) What is the antibody dilution and incubation time employed for the primary antibody? 1/200, incubation time was 1 hr.
3) Which blocking reagent was used? We use 10% FBS.
4) Is the secondary antibody working well with other primaries? yes, we used this secondary with your previous batch of this ab from you as well as for several other antibodies, which all worked fine.
5) Did you try out both vials? If not, I'd suggest trying the second vial as well as the issue could be just vial-related. We did try both.
6) Were there any changes donein your sample preparation or protocol when using the old lot and the newlot? No, we have used your SMN ab extensively for years.

What kind of replacement were you looking for? We have 1 vial of a different lot in stock currently which I can send you. Alternatively, a different Gemin1 antibody can be sent free of charge. We would like to try both since we paid for two and spent so much time already on this problem. We need to get the expt done. Thank you for your understanding.
Please let me what you would prefer. Thank you so much! Can we get it by tomorrow please.
