Cultrex HA-R-Spondin1-Fc 293T Cells Summary

Stably transfected 293T cells expressing murine R-Spondin 1 that have an N-terminal HA epitope tag and are fused to a C-terminal murine IgG2a Fc fragment.

Why Use Cultrex HA-R-Spondin1-Fc 293T Cells?

Roof plate-specific Spondin-1, (R-Spondin 1, RSPO1, or CRISTIN3), is a 27 kDa secreted activator protein that belongs to the R-Spondin family. R-Spondin positively regulates Wnt/beta-catenin signaling by acting as a ligand for Lgr4-6 receptors and as an inhibitor for ZNRF3. R-Spondin 1 induces proliferation of intestinal crypt epithelial cells, increases intestinal epithelial healing, and supports intestinal epithelial stem cell renewal. Cultrex HA-R-Spondin 1-Fc 293T Cells are stably transfected to express murine R-Spondin 1 that contains an N-terminal HA epitope tag and is fused to a C-terminal murine IgG2a Fc fragment.

Cultrex HA-R-Spondin 1-Fc 293T cell line can be used to produce either purified R-Spondin 1 or R-Spondin 1-conditioned media. The murine R-Spondin 1 protein produced from this cell line has been used extensively in organoid culture to maintain Lgr5+ stem cells. The Fc and HA tags can be used for protein purification or characterization.

  1. Murine R-Spondin 1 is reported to be a 27kDa protein, but the protein produced by the 293T cells in Catalog # 3710-001-01  is 70-75 kDa. Why?

    • The natural R-Spondin 1 protein is approximately 27 kDa. The cells in this product express a construct containing both an additional HA-tag plus an Fc fragment, hence the much larger size.

  2. For culturing and handling of the Cultrex HA-R-Spondin1-Fc 293T Cells (catalog # 3710-001-01), does the Fetal Bovine Serum need to be heat-inactivated in the Basal Growth Medium or Freeze Medium?

    • Heat-inactivated serum is not required for either of these media.

  3. Has this cell line been tested for mycoplasma?

    • Yes, all retail lots are tested to confirm mycoplasma is undetected by PCR, which is documented on the lot-specific CoA.
