Recombinant human noggin protein

QK034

Brand: Qkine

Human noggin is a bone morphogenetic protein (BMP) antagonist which regulates cell differentiation and growth. Noggin is used in the culture of intestinal, pancreatic, lung and tumor-derived organoids and the maintenance of undifferentiated embryonic stem cells (ESC) and for stem cell differentiation into neural and microglial lineages.

Qkine human noggin (Qk034) is a highly pure, animal origin-free, bioactive 46 kDa dimer for reproducible results in organoid culture.

Featured applications

  • Tumor organoid culture
  • Epithelial organoid culture (WNR media)
  • Stem cell differentiation into neural and microglial lineages

Bioactivity

Human noggin is a BMP inhibitor, and its activity is determined by inhibition of BMP-2 (Qk007) activity in a BMP-2 responsive firefly luciferase reporter assay. HEK293T cells are treated in triplicate with a serial dilution of noggin and a standard concentration of BMP-2 for 6 hours. Firefly luciferase activity is measured and normalized to the control Renilla luciferase activity. EC50 = 1.5 nM (70.1 ng/ml). Data from Qk034 lot #104291.

Purity

Noggin protein (Qk034) has an unusual migration in non-reduced (NR) SDS-PAGE due to the non-covalent dimer which is the active protein. Similar migration in SDS-PAGE is seen for gremlin-1, a related BMP antagonist. The identity of the purified dimeric protein was confirmed using mass spectrometry. Upon reduction, the protein monomer migrates at 23 kDa. Purified recombinant human noggin protein (7 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 Qk034 lot #104285.

Qkine human noggin is as biologically active as a comparable alternative supplier protein. Quantitative luciferase assay with Qkine human noggin (Qk034, green) and alternative supplier noggin (Supplier B, black) inhibition of BMP-2 (Qk007). Cells were treated in triplicate with a serial dilution of noggin and a standard concentration of BMP-2 for 6 hours. Firefly luciferase activity was measured and normalized to control Renilla luciferase activity.


Protein background

Noggin is a 64 kDa homodimeric glycoprotein expressed during embryonic development and in adult cells [1]. Noggin is an extracellular antagonist of BMP cell signaling. BMPs are part of the larger TGFβ family and regulate embryonic, fetal and adult development in all vertebrates [1, 2]. Noggin binds to BMP-2, -4, -6 and -7, preventing interaction of the ligands with their receptor, and consequently blocking downstream activation of signaling cascades [2,3].

Through its control of BMP signaling, noggin plays a crucial role in embryonic patterning, as well as in the development of the neural tube, teeth, hair follicles, and the eye [4]. In cell cultures, noggin is used in the maintenance of pluripotent stem cells, differentiation of iPSCs to neural lineages, and in a large variety of organoid culture systems including intestine, liver and lung organoids [4, 5].
