Qk007 BMP2 (human) Qkine protein vial
recombinant human/mouse/rat/bovine/porcine BMP-2 protein (Qk007)£160.00£2,400.00

Human/mouse/rat/bovine/porcine BMP-2 protein (bone morphogenetic protein 2) protein is member of the TGFβ family and a key regulator of embryogenesis and potent differentiation factor of embryonic stem cells (ESC) and induced pluripotent stem cells (iPSC) towards endoderm fates. BMP-2 plays roles in the differentiation of mesenchymal cells to adipocytes, epithelial cancer EMT, chondrogenesis and regulation of neuronal and glial cell development.

26 kDa disulfide–linked bioactive highly pure dimer comprised of the mature domain of human BMP-2 protein. Animal-free (AOF) and carrier protein-free.

recombinant FGF2-G3 145 aa protein (Qk052)
recombinant FGF2-G3 145 aa protein (Qk052)£120.00£3,000.00

FGF2-G3 (145 aa) protein is a thermostable engineered form of FGF-2 (bFGF). Qk052 comprises the 145 aa form of FGF-2 (Qk025) with the nine amino acid substitutions developed by Dvorak et al. 2018. This increases the functional half-life of the protein from <10 h (wild-type) to >7 days (FGF2-G3 145 aa).

FGF2-G3 is used in B8 media (Kuo et al. 2019) for weekend free, high homogeneity induced pluripotent stem cell culture. This new 145 aa thermostable FGF-2 protein allows direct comparison of efficacy in systems using FGF-2 145 aa (Qk025) for chemically defined stem cell and organoid culture media, and cultured meat media development.

High purity 16 kDa bioactive FGF2-G3 145 aa protein. Animal-free (AOF), carrier protein-free and with no His-tag.

recombinant FGF2-G3 protein (Qk053)
recombinant FGF2-G3 protein (Qk053)£120.00£3,000.00

FGF2-G3 (FGF2-STAB®) protein is a thermostable engineered form of FGF-2 (bFGF). Qk053 is the 154 aa mature domain of FGF-2 (Qk027) with nine amino acid substitutions to enhance stability without impacting bioactivity developed by Dvorak et al. 2018. This increases the functional half-life of the protein from <10 h (wild-type) to >7 days (FGF2-G3).

FGF2-G3 is used in B8 media (Kuo et al. 2019) for weekend free, high homogeneity induced pluripotent stem cell culture. FGF2-G3 also has applications in chemically defined stem cell and organoid culture media, and cultured meat media development.

High purity 17 kDa bioactive FGF2-G3 protein. Animal-free (AOF), carrier protein-free and with no His-tag.

recombinant mouse FGF-2 (bFGF) protein (Qk042)
recombinant mouse FGF-2 (bFGF) protein (Qk042)£100.00£600.00

mouse FGF2 / bFGF protein is an important factor in the maintenance of mouse epiblast-derived stem cells (EpiSC). Mouse naïve pluripotency is maintained by LIF, BMP4, and Wnt signalling pathways. However, the primed state of pluripotency in mouse EpiSCs is more similar to hESC and hiPSC, being maintained by FGF2 and TGFβ/Activin/Nodal pathways.1,2

High purity and bioactivity 16 kDa murine bFGF / FGF2 (basic FGF) protein, animal-origin free (AOF) and carrier-protein free (CF).

Qk018 LIF (mouse) Qkine protein vial
recombinant mouse LIF protein (Qk018)£120.00£1,600.00

Mouse LIF (murine leukemia inhibitory factor) protein maintains the pluripotency and self-renewal of mouse  embryonic and induced pluripotent stem cells.

Qkine recombinant mouse LIF protein is animal-free and carrier-protein free for highly reproducible results. Bioactivity was tested by colony formation assay and determination of Nanog expression.1

Qk033 Noggin (mouse) Qkine protein vial
recombinant mouse/rat noggin protein (Qk033)£160.00£2,400.00

Mouse/rat noggin is a bone morphogenetic protein (BMP) family antagonist used in the culture of intestinal, pancreatic, lung and tumor-derived organoids, maintenance of undifferentiated embryonic stem cells and for stem cell differentiation into neural and microglial lineages.

Qkine recombinant mouse noggin protein is a highly pure 46kDa bioactive dimer for reproducible results (animal-free and carrier-protein free).
