  • Recombinant human Activin A (HZ-1138) causes dose-dependent inhibition of proliferation in the Mouse plasmacytoma (MPC-11) cell line. Proliferation of the MPC-11 cell line was assessed using Promega CellTiter 96®. MPC-11 cells were treated with increasing concentrations of recombinant human Activin A for 72 hrs hours before addition of CellTiter96® reagent. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 values range from 0.5-3.5 ng/ml.

  • Human induced pluripotent cells(iPSCs) were differentiated to definitive endoderm using HumanKine growth factors (Activin A- HZ-1138, bFGF-HZ-1285, BMP-4- HZ-1045, and Wnt3A-HZ-1296). The differentiation was confirmed by detection of expression of FOXA2(Red) and downregulation of pluripotency marker NANOG(yellow), in immunofluorescence

Background

HumanKine Activin A is a high-quality, animal-free recombinant human protein widely used in stem cell research, cell culture, and signaling pathway studies. Produced in HEK293 cells, it is designed to deliver exceptional purity, strong bioactivity, and low endotoxin levels for consistent experimental performance. HumanKine Activin A supports applications such as stem cell differentiation, tissue development, regenerative medicine research, and advanced biological assay development. Activin A is a dimeric growth factor within the TGF-β superfamily that engages specific type II and type I receptors to initiate SMAD2/3 signaling cascades and downstream transcriptional regulation. Functionally, Activin A is a key regulator of pluripotent stem cell maintenance and a potent inducer of definitive endoderm formation Its reliable human-like glycosylation profile makes it a preferred choice for researchers seeking reproducible results in sensitive cell-based workflows.(PMID 16885530, 8200957)
