I have placed an order for you, however the antibody is currently out of stock; we are expecting it to be in stock on 17th July and will then be dispatched.

Please quote the order number "1122106" to our customer service team for any order related inquiry.

I hope this new vial will be OK. Please do not hesitate to contact me if you don't receive the product in time or if the product fails again.

Have a good weekend!

Thank you very much for having patience!

I have requested the exact immunogen information from our collaborator and is now waiting a reply from them. I will send you the details soon.

Currently, we do not have explanation for 120 kDa band; this could be due to non specificity of antibody or due to lysates. The antibody however should detect a 30-35 kDa band.

The idea for replacement was to try a different lot and then seeing, if the new lot gives same result; if yes, then it will be worth identifying the 120kDa band.

We do not have new lot instock however I have requested the lab for its avialability.

Thank you very much for providing the protocol details and images.

The protocol seems fine to me however the following protocol optimizations could;

- At Abcam we use 5% BSA for blocking; I would recommend trying BSA instead of milk.
- Boil the lysates for 10 minutes at 100C.

We are not sure about the identity of 120 kDa band so I am sorry we will not be able to comment on this. The immunogen of this antibody is from the N-terminal region of human CXXC5 (http://www.uniprot.org/uniprot/Q7LFL8; this database actually shows 2 isoforms of CXXC5).

I can offer you a different replacement antibody if you would like to compare the results. Could you let me know how you would like to proceed.

Thank you very much for sending the details. I have sent an email to my colleague in lab and requested new QC data for this lot. I will contact you with the explanation soon.

Thank you for contacting us.

I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. This information will also allow us to investigate this case internally and initiate additional testing where necessary. If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody.

I look forward to receiving your reply.
