  • Function

    Major connective tissue mitoattractant secreted by vascular endothelial cells. Promotes proliferation and differentiation of chondrocytes. Mediates heparin- and divalent cation-dependent cell adhesion in many cell types including fibroblasts, myofibroblasts, endothelial and epithelial cells. Enhances fibroblast growth factor-induced DNA synthesis.

  • Tissue specificity

    Expressed in bone marrow and thymic cells. Also expressed one of two Wilms tumors tested.

Answer

Thank you for contacting us.

I can confirm that ab50044 can be used as a control in sELISA involving ab84244 and ab109606.

Please be advised the conditions and dilutions has to be determined by end use.

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

Question

I am sorry that I don’t catch your meaning exactly. Do you means the two products can both use to promote the cell’s Proliferation or adhesion? Or they have different use because “they are different fragments of the CTGF”?   Thank you very much for your reply! --

Answer

My previous statement was incorrect. These, ab50044 and ab61847, appear to be the same fragment, but it is not clear to me if both products have both been assayed for activity. Only the ab50044 datasheet includes a note about stimulation of HUVEC proliferation. We are not aware of any testing of stimulation of fibroblast proliferation. Here are links to the two datasheets for ab50044 and ab61847: Click here (or use the following: https://www.abcam.com/Recombinant-human-CTGF-protein-ab50044.html). Click here (or use the following: https://www.abcam.com/CTGF-protein-Active-ab61847.html). From the ab50044 datasheet: Recombinant fragment, corresponding to amino acids 253-350 of Human CTGF, a 11.2 kDa protein of 98 amino acid residues which exerts full heparin binding, cell adhesion, and mitogenic CTGF activity. Biological Activity : Determined by the dose-dependent stimulation of the proliferation of HUVEC cells. The expected ED50 for this effect is 1.0-2.0 µg/ml. Farther down on the datasheet, the sequence is specified: MGKKCIRTPK ISKPIKFELS GCTSMKTYRA KFCGVCTDGR CCTPHRTTTL PVEFKCPDGE VMKKNMMFIK TCACHYNCPG DNDIFESLYY RKMYGDMA From the ab61847 datasheet: Recombinant C-terminal fragment (Human) containing 98AA. MW: 11.2 kDa. MGKKCIRTPK ISKPIKFELS GCTSMKTYRA KFCGVCTDGR CCTPHRTTTL PVEFKCPDGE VMKKNMMFIK TCACHYNCPG DNDIFESLYY RKMYGDMA These are actually the same fragment, though only the ab50044 datasheet has the note about activity testing. I know this may not answer all your questions; please reply if you need more infomation.

Question

Thank you very much for your reply!   Do you mean the "CTGF fragment ab69786" is just use in western blotting, and it doesn't have activity to promote the function of the fibroblasts? Do you think ab61847 and ab50044 are suitable for my research purpose? I have seen that the ab61847 and ab50044 are for "SDS-PAGE ". Which is the difference between the two products?

Read More
Answer

The protein ab69786 has not, to our knowledge, been tested for activity. The other two are the same fragment, different from the ab69786 fragment, and both appear to have been tested for activity, though only the ab50044 datasheet mentions the testing and lists functional assays as an applicaton. Please let me know if you have other questions.
