Question (26950) | Anti-CGRP antibody (ab47027)

Go to datasheet (ab47027)


Customer is seeing only a diffuse band at the expected size of 15 kDa on rat ganglia samples and a strong band ~30 kDa.  Loading 20ug sample, running tubes for 10 minutes on denaturing program on PCR machine.  Using 1 ug/ml for staining with primary. Question for lab: How was tissue solubilized?


Thank you for calling today, it was a pleasure speaking with you! As we discussed over the phone, your protocol sounds reasonable and you are using the antibody on tissue we have tested in-house.  I'm unsure of why the antibody is not working on your samples, and apologize for the difficulty you've encountered.  As we discussed, checking the denaturing program might be a good idea just to ensure that you're fuly denaturing the proteins in the sample to prevent any dimers or complexes. I have arranged for you to receive a free vial of a different lot of the antibody on order number ######.  This should arrive to you tomorrow. Please let me know how you fare with the new vial, I'll be curious to know if the new lot makes a difference!  If you have any other questions, please do not hesitate to contact us.  Have a great evening!
