  • Function
    Functions as a GTPase-activating protein specific for Rho and an activator of PLCD1 in vivo and induces morphological changes and detachment through cytoskeletal reorganization.
  • Tissue specificity
    Highest level of expression in the spleen, with rather lower levels in prostate, testis, ovary, small intestine and colon, but none in the thymus.
  • Sequence similarities
    Contains 1 Rho-GAP domain.
    Contains 1 SAM (sterile alpha motif) domain.
    Contains 1 START domain.

  • ab21200 (5 µg/ml) staining DLC1 in Human Adrenal Gland by IHC-P.  Steamed antigen retrieval in citrate buffer pH6, AP-staining.  This image shows strong reticulate staining in the cytoplasm of medular cells.

  • ab21200 staining DLC1 in Human oral cancer and adjacent normal tissue by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections).

    Tissue was fixed with formaldehyde and blocked with 1% BSA for 1 hour at 27°C; antigen retrieval was by heat mediation with citrate buffer. Samples were incubated with primary antibody (in 1% BSA in TBS) for 18 hours at 4°C. A biotinylated rabbit polyclonal was used as the secondary antibody.

Thank you for contacting us. I am sorry to hear that you have been experiencing problems with the ab21200. In IHC-P most of the time problem lies in antigen retrieval step. This step is very crucial for IHC-P, so we always recommend our customers implementing proper troubleshooting steps that help to get the right staining of target by exposing the antigen fully. I have attached the general protocol we used to test this antibody in IHC-P: https://www.abcam.com/ps/pdf/protocols/ihc_p.pdf https://www.abcam.com/index.html?pageconfig=resource&rid=11488#1 I can also help you with troubleshooting however I would need complete information of protocol being used. I have attached a questionnaire where we have added all the selected questions that we need to understand the problem quickly. Once I receive the questionnaire I will then suggest changing the steps to get optimized results. Click here (or use the following: https://www.abcam.com/index.html?section=ihc&pageconfig=technical&intAbID=21200&mode=questionaire) I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
