I am the technical support specialist of Jingmei Biotech Co., Ltd., China. One of my custormers wants to require two products, the Cat:ab31127 and ab15072. He wants to know titers and sensitivities of the products. He ordered the product, Cat:ab15072, and could not detect the positive control(0.2ng). The positive control(0.2ng) can be detected by another antibody made in R-Biopharm in Germany. Now he wants to pruchase a lot of the two antibodies, so I desire you can offer the introductions. Looking forward to your reply! thanks!

Thank you for your enquiry. With regards the titres and sensitivities of ab15072 and ab31127 I can tell you that both antibodies are unlikely to detect 0.2ng/ml as this is significantly lower than the detection threshold. I have emailed some data of ab31127 in a follow up email. I contacted the source of ab15072 and in the opinion of the originator this is 0.2ng/ml is below the detection threshold. In their opinon they would be surprised if 1ng/ml would be detected. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
