Application Abreviews Notes

IHC-P Use at an assay dependent concentration.


  • Function
    Transcription regulator that acts as a key regulator of lineage commitment of immature T-cell precursors. Necessary and sufficient for commitment of CD4 lineage, while its absence causes CD8 commitment. Development of immature T-cell precursors (thymocytes) to either the CD4 helper or CD8 killer T-cell lineages correlates precisely with their T-cell receptor specificity for major histocompatibility complex class II or class I molecules, respectively. Transcriptional repressor of the collagen COL1A1 and COL1A2 genes. May also function as a repressor of fibronectin and possibly other extracellular matrix genes.
  • Sequence similarities
    Contains 1 BTB (POZ) domain.
    Contains 4 C2H2-type zinc fingers.

The better choice will be ab70991, as the immunogen is 100% conserved in rat ThPok. The immunogen for ab23388 is conserved 85%, so reactivity is predicted, but is less probable than ab70991 reactivity.

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:

Thank you for your enquiry.

I am sorry to confirm that non of our thPok antibodies have been tested and guaranteed in Xenopus tropicalis. I have checked the alignment of the sequence you kindly provided with the immunogen sequences for the antibodies we have. Regrettably, these all show very low alignment which means the antibodies are very unlikely to detect in Xenopus tropicalis.

I am sorry this is not better news and that we do not have antibodies that would meet your requirements on this occasion.

If you have any further questions, please do not hesitate to contact us.

Thank you for your enquiry. We do not routinely offer free or trial sized samples for testing purposes. Our policy at Abcam is that if an antibody does not work as specified on the datasheet, we will offer a replacement or reimbursement. To our knowledge, this antibody has not yet been tested with murine samples. However, I did a sequence alignment of the amino acid range listed for the immunogen and the murine sequence, and found that there is 85% homology within that range, with long stretches of matching amino acids. So it is possible that the antibody will cross-react. Should you decide to go ahead and purchase this product, please let us know how you get on by submitting an Abreview and in return we will offer you 50 Abpoints which can be redeemed on a number of rewards (a further 100 Abpoints will be offered for an image). I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Thank you for your phone call. The sequence of the synthetic peptide used for immunization is as follows: AQGGGPPLSPEELGSDEDAIDPDLMAYLSSLHQDNLAPGLDSQDKLVRKRRSQMP. It represents a part of a region from AA residue 291 to AA residue 345 of ZFP67 (NP_056956 in NCBI database). If you have any additional questions, please contact us again.
