Trascruz reagents for ChIP assays - (Aug/17/2005 )
I have noticed that the Santa Cruz antibody I use for western blotting also has a "Transcruz reagent for ChIP assays" listed on the product sheet. I tried calling the tech help people at SC to ask exactly what this was, but they were unable to tell me ANYTHING! Can anyone elighten me?
I believe Transcruz means you can order the same antibody but in a super concentrated form. Such a concentrated stock is necessary for some applications such as gel supershifts. If you order the antibody Transcruz, it's the same catalog number but with an "x" at the end.
Call Santa Cruz again and maybe you'll get someone more knowledgable to confirm.
thanks for that! I might give it a try!
Good afternoon to Nay and ChIPster from Technical Service here at Santa Cruz Biotechnology:
First, thank you to ChIPster for clarifying our X products. You are absolutely correct that they are provided more concentrated-specifically 200 ug in 100 ul (the non-X forms are provided at 200 ug in 1 ml). In addition, they do not contain gelatin (which is used in the non-X forms as a stabilizing protein).
Second, to Nay, what information did you ask for, and what information was not provided to you? It says that we were not able to tell you ANYTHING. We find this difficult to believe. Perhaps you could let us know specifically what you are looking for and we will give you as much information as we have. If we are unable to answer your question due to lack of data, we will let you know rather than attemtping to misinform a customer. We are here to serve you. Please let us know how we can help.
In addition, if you are ever dissatisfied with a response, please let us know that we did not provide you with the information you requested. If need be, you can ask to be transfered to a supervisor, who will be more than willing to discuss your experience as well as answer any questions you may have.
Our email is firstname.lastname@example.org and our phone number is 1-800-457-3801 ext. 2.
Thank you for your time in reading this response.
