The 3dGRO L-WRN Conditioned Media Supplement is a formulation based on DMEM/F-12 PLUS medium containing the 3 growth factors Wnt3a, R-spondin-3, and Noggin. These factors act upon the Wnt signaling pathway, which plays a critical role in sustaining the proliferation of LGR5+ crypt stem cells within organoids. Wnt activation is thus essential for in vitro growth of human gut organoids. L-WRN conditioned medium is widely used as a component of the culture medium for supporting the growth of human intestinal organoids including the 3dGRO gastrointestinal organoid biobank (SCC310-SCC367). Applications for L-WRN conditioned medium include but are not limited to the expansion of human intestinal gut organoids and other epithelial organoid cell types.

Note: Product is supplied at a 2X concentration (see datasheet for a complete organoid media recipe).

The 3dGRO L-WRN Conditioned Media Supplement is derived from the Mus musculus L-M(TK-) cell line secreting mouse Wnt3a, R-spondin-3 and Noggin. L-WRN Conditioned Medium may contain trace amounts of mouse DNA.

Features and Benefits

L-WRN conditioned media supplement containing the 3 growth factors Wnt3a (W), R-spondin-3 (R), and Noggin (N) for organoid cultures.

Storage and Stability

The 3dGRO L-WRN Conditioned Media Supplement should be stored at -20°C. When ready to use, thaw the L-WRN Conditioned Medium overnight at 2-8°C in the dark. Thawed medium is good for two weeks when stored at 2-8°C. If media will not be used within two weeks, aliquot unused media and store at -20°C. After thawing refrozen aliquots, do not re-freeze media.
