Customer reviews and Q&As


Thank you for taking the time to complete our questionnaire and contact us. I am sorry to hear the customer hashad difficulty obtaining satisfactory results from this Anti-SGSM3 antibody.

The details kindly provided will provide us with vital information for our monitoring of product quality.

Indeed, I agree that the band for SGSM3 should be expected at 85 kDa (or 88 kDa for isoform 2). To be honest, I do nothave a goodexplanationwhy the customer observes a band at 70 kDa. It might have something to do with the nature of the samples: human carcinoma cells often exhibit genetic mutations that may lead to the expression of a truncated protein or a fusion protein of a different size than expected. However, this is not very well documented so far. As the protocol used by the customer seems fine to me, I am happy to offer the customer a free of charge replacement. This could either be a new vial of ab104504, or I may recommend a vial of our alternative SGSM3 antibody ab99422 to verify the results.

Otherwise, I am happy to send any other primary antibody or issue a credit note in compensation.

Thank you for your cooperation. I look forward to hearing from you with details of how the customer would like to proceed.
