    Ab108400 was shown to recognize Calpain 1 in wild-type HAP1. A faint cross-reactive band was observed in  CAPN1 (Calpain 1) knockout cells at 82 kDa when over-exposed. Due to the immunogen’s homology with CAPN2 (Calpain 2 Uniprot: P17655), this band could correspond to the Calpain 2 protein. Please note that cross-reactivity with this protein has not been confirmed experimentally.

Answer

Thank you for taking time to complete our questionnaire. I am sorry to hear that this antibody is not providing satisfactory results.

The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality.

Having reviewed this case, I would like to offer some suggestions to help optimize the results from ab108400.


How long did they perform the antigen retrieval in the pressure cooker? They may have over-retrieved so they can decrease the amount of time.


They should also omit any permeabilization agent like Triton X-100.


I see that the customer only blocked for 5 - 10 mins and this may be too short of a time. What buffer have they tried and at what percentage? They should block with 10% serum for 1 hr at RT.


They may also want to try diluting the antibody more to 1:2000 or 1:5000 and incubate that overnight at 4C instead of 1 hr at RT.


Have they run a no primary control?


Should the suggestions not improve the results, please do let me know.

In the event that a product is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund.

I hope this information is helpful, and I thank you for your cooperation.
