HEK-293 whole cell lysate (ab7902)

We do supply the positive control for the Anti-S6K1 (phospho T229) antibody (ab5231).


The positive control is HEK293 (Human embryonic kidney cell line) Whole Cell Lysate (ab7902). Please refer to the Cell Lysate datasheet for further information.

Thank you for contacting us.

HEK293 cells can also be used as positive control.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for contacting us. I am sorry for the confusion. I was unsure whether you wanted replacement product or a credit note/refund. I have issued credit notes/refunds for these products. Your credit note ID for AB93922 is xxx. Your credit note ID for AB7902 is xxxxx. I am sorry that this antibody did not perform as stated on the datasheet. I have asked our accounting department to issue a credit note for you, which can be redeemed against the invoice of a future order by passing it on to your purchasing department. To avoid confusion, please ensure your accounts department is aware of how the credit note is being used. If you have questions on how to use the credit note, please contact our accounting department. If payment has already been made on the original order and you wish to receive a refund, please ask your purchasing department to contact our accounting department so that we may gather the correct information needed for the refund. To avoid confusion, please ensure your accounts department is aware of how the credit note is being used. Our accounting department can be contacted by email at us.credits@abcam.com or by telephone using the information at the Contact Us link in the top right corner of our website. Please refer to the credit note ID in any correspondence with our accounting department. The credit note ID is for your reference only and does not automatically guarantee the credit. I hope this experience will not prevent you from purchasing other products from us in the future. Our Scientific Support team is always at your service, should you require further expert advice.

Thank you for sending this information.

If you would like, I can issue free of charge replacements of the antibody and lysate with another anti-ThPok antibody such as ab23388 or ab70991 and our recommended positive control lysate. Like ab93922, these antibodies will be covered by our Abpromise guarantee for use in WB on human tissues.

As neither antibody has been tested in FACS, I would be glad to also enroll either of these products in our AbTrial program for that application. Here is a brief description of how this program works:

The testing discount program is for customers who like to use an antibody/protein on an untested species/application. You would purchase the antibody at full price (in this case I would be providing a product as a free of charge replacement), test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody at the full price (100%) of the antibody you have tested. The terms and conditions applicable to this offer can be found here:https://www.abcam.com/AbTrial

We feel that an HRP- ECL detection system will generally be adequate for use with our WB tested products unless stated on the datasheet. We do not have specific FACS recommendations as we have not yet tested these in that application. I can recommend a starting concentration of 1ug/ml; however the optimal concentration will have to be found experimentally. Our direct and indirect FACS protocols may be found at the following locations:

Direct:https://www.abcam.com/index.html?pageconfig=resource&rid=11380

Indirect:https://www.abcam.com/index.html?pageconfig=resource&rid=11381

More protocol information may be found at:

I hope this information is helpful to you and look forward to hearing how you would like to proceed. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your message and for providing this further information.

I am sorry to hear the suggestions made have not improved the results on this occasion. I appreciate the time you have spent on these experiments, and would like to offer refund or credit note in compensation (providing the product has been purchased in the last 180 days of contacting us). In order to arrange this, I would appreciate if you could confirm your order numbers or PO and dates of purchase for these antibodies and lysate?

We believe that any product which has been tested for ThPOK in WB should perform as stated in the datasheet which is why we offer our Abpromise guarantee. We do have other products which are tested in WB but unfortunately none have also been tested in FACS. When choosing a product which may have the best chance to work in both applications I would suggest using a product which has been tested in ICC, IHC or IP as well as in Western blot. Two products which may perform best in both WB and FACS may be:

AB70991https://www.abcam.com/ThPok-antibody-ab70991.html

AB23388https://www.abcam.com/ThPok-antibody-ab23388.html

Thank you for your continued cooperation. I look forward to hearing from you with details of how you would like to proceed.

Thank you for your telephone inquiry this afternoon. I am sorry to hear you have experienced difficulty obtaining satisfactory results from this antibody in western blotting.

I do hope the use of a new secondary antibody will resolve this issue for you. However should these issues continue please know that this product is covered by our Abpromise guarantee. We are happy provide scientific support at any time. If you are using the product in species and applications listed on the datasheet and contact us within six months of purchase, we are also happy to replace or refund the product should we not be able to help you to resolve the issue. More information on our Abpromise may be found at the following link:

Please let me know if you have any questions or there are other ways that Abcam may help you meet your research goals.

Thank you for contacting us. I presume you are looking for positive control used in western blot. Our customers have used this ab successfully with mouse brain tissue and 293 cells lysates. Please check the Abreviews. The Mouse brain lysates can be found with catalogue numbers are; ab7189, ab7190 ab30151 and Human 293 cell lysates with catalogue number ab7902. Please also click the following link to see the tissues which express CDK2 target, lysates of these can be used as positive control. http://www.proteinatlas.org/ENSG00000123374/normal http://www.proteinatlas.org/ENSG00000123374/cancer http://www.proteinatlas.org/ENSG00000123374/cell We have the tissue lysates in catalogue. Please type "lysates" in the product search box provide on the Abcam homepage and system will give you sorted products as per your requirements. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry. I am sorry to hear that you have been having difficulties with this antibody. Unfortunately we do not sell the positive control employed as a positive control for ab22510; HEK293 cells overexpressing human FOXP3. However, we do sell Tonsil (Human) Cytoplasmic Lysate - tumor tissue (ab29606) and tonsil is known to express high levels of FOXP3. It would help me if you could provide me with further information of the protocol that you have been using by clicking on the link below and filling in our technical questionaire. This will better enable our technical team to determine the steps that you have taken to optimise this antibody. It would also be most informative if you could provide me with a representative blot and details of the batch number. https://www.abcam.com/index.html?section=western&pageconfig=technical&intAbID=7902&mode=questionaire I look forward to hearing from you.

I'm sorry but we do not currently stock RIPA buffer.
