      Prostate cancer is the most frequently diagnosed cancer and is the second leading cause of cancer-related deaths in American men. Although the early serum detection of prostate-specific antigen (PSA) plays important roles in early diagnosis, it may not distinguish prostate cancer from benign diseases. Recently, a novel protein, which contains 339 amino acids, named STEAP (six transmembrane epithelial antigen of the prostate), was identified in advanced prostate cancer. STEAP is unique among the currently known prostate cancer markers because of its putative secondary structure, from which one may predict that it functions as a potential channel protein. STEAP is strongly expressed in advanced prostate cancer and some extent expression in other cancers, such as colon and ovarian cancer cell lines.

      The Life Science industry has been in the grips of a reproducibility crisis for a number of years.

      Question

      Sorry for the delay, however I just heard back from the customer after several contact attempts. I have attached their answers to your questions. In answer to your questions: 1) We see many non specific bands (please see picture attached for a sample) 2) Antibody is being tested on EL-4 (mouse T cells) that have been transfected with pcDNA3 encoded with human STEAP. WB was done on whole cell extract. 3) Sample were lysed with SDS, protease inhibitors, b-mercapto, EDTA, etc. Samples were heated for 10 min at 100'C. 4) Ab was raised against Human STEAP. Dilutions used were 1/500, 1/1000, 1/2000, 1/6000. Incubation time of 1hour followed by three thorough washing steps. 5) Secondary antibody is an anti-rabbit. Incubated for 45 min followed by three thorough washing steps. Secondary antibody is commonly used by numerous members of our lab with no problems. 6) ECL kit. 7) Secondary antibody has been run alone (with no primary antibody) and shows no background whatsoever. Blocking and washing steps are sufficient and stringent. We block o/n with agitation at 4 degrees. Washing is has been done 3 times for 10 min each, or 6 times for 5 min each. Bands cannot be degraded products as they are at a higher molecular weight then the full-length expected Band size. 8) Westerns were done many times with the same results. Altered steps were washing times, antibody concentration, altered incubation times. 9) Negative controls showed the same result to a lesser intensity.no positive controls were used. Just to recap, this is the customer that found the same result with his transfected and non-transfected cells (control) and saw no difference in staining. He does not get the 40kDa band that he expects to see (I will ask to see if the customer can show the MWts of the control bands), but a lot of other bands instead. Customer is very unhappy and wants a credit. I look forward to your response,
