recombinant human BMP-4 protein (Qk038)
Human BMP4 (bone morphogenetic protein 4) protein is a key regulator of embryogenesis and supports the differentiation of embryonic stem cells and induced pluripotent stem cells. In addition, BMP4 plays roles in the differentiation of mesenchymal cells to adipocytes, epithelial cancer EMT, and regulating neuronal and glial cell development.
Highly pure 26 kDa disulfide–linked bioactive dimer comprised of the mature domain of human BMP4 protein (animal-free and carrier protein-free).

bioactivity
Bioactivity is determined using a BMP4-responsive firefly luciferase reporter in stably transfected HEK293T cells. Cells are treated (in triplicate) with a serial dilution of BMP4 for 6 hours. Firefly luciferase activity is measured and normalized to the control Renilla luciferase activity. EC50 = 0.728 ng/ml (30.16 pM). Data from Qk038 lot #104294.
purity
BMP-4 (Qk038) dimer migrates as a single band at 24 kDa in non-reducing (NR) and 13 kDa as a single monomeric species upon reduction (R). High purity yield of dimeric protein (bioactive form).
Purified recombinant protein (3 μg) was resolved using 15% w/v SDS-PAGE in reduced (+β-mercaptoethanol, R) and non-reduced conditions (NR) and stained with Coomassie Brilliant Blue R250. Data from Qk038 lot #104294.
further quality assays
mass spectrometry: single species with expected mass
analytical reversed-phase: single sharp peak
endotoxin: <0.005 EU/μg protein (below level of detection)

protein background
Bone morphogenetic protein 4 (BMP4) is part of the TGFβ superfamily of growth factors. BMP4 is a key regulator of embryogenesis with roles in gastrulation, establishment of a dorsal-ventral axis, and regulation of limb development (1). As their name suggest the BMP family is involved in the development and maintenance of bone and cartilage; in adults BMP4 has roles bone and cartilage metabolism, as well as neurogenesis (2) and hematopoietic stem cell homing (3). BMP4 acts through two serine-threonine kinase receptors; Bone morphogenetic protein receptor (BMPR) 1 and BMPR2. Via these receptors BMP4 invokes Smad and map kinase pathways and consequently alters target gene transcription (4).
