Thank you for your reply. If you would like, we can obtain the blocking peptide from the original laboratory. This is a product that you would have to purchase. If you are interested, I can add this product to our catalog for you to purchase from us. We are confident that the higher MW bands are aggregated products and we have seen them in cells transfected with CTR1 gene. The exact nature of aggregation is not clear but could represent covalent coupling as they still appear in reduced condition. Unfortunately, we are not able to provide a positive control. We would recommend intestinal epithelial cells. We've also tested the product in various ovarian cancer cell lines with positive results. I hope this information is helpful. Please do not hesitate to contact us if you have any additional questions.

Thank you for contacting Abcam regarding ab108481. I am sorry that you are experiencing difficulties with this antibody in WB. I have reviewed your protocol information and the image of your blot. I have some suggestions that may explain your results. SLC31A1 is a protein that is glycosylated and therefore, higher molecular weight bands are expected. I am not sure about the glycosylation states in the cell lines you are examining, but I would recommend researching this further in the primary literature. I have attached an image showing the various bands recognized by this antibody due to glycosylation. At this time, this is the only antibody we have against this target and we are not able to generate one against a different portion of the protein. I hope this information is helpful. Please do not hesitate to contact us if you have any additional questions.
