  1. Recombinant Human FGF19 Protein
      种属: 人(Human)    Accession #: O95750    
      表达系统: E. coli    蛋白标签: N-His    内毒素水平: <1.0 EU/μg    
      生物活性: FGF19 is a member of the fibroblast growth factor (FGF) family. FGFs are heparin-binding growth factors with a core 120 amino acid (aa) FGF domain that allows for a common tertiary structure. In general, FGFs are expressed during embryonic development and in restricted adult tissues. Human FGF-19 cDNA predicts a 251 aa precursor protein with a 22 aa signal peptide and a 229 aa secreted mature protein with no potential N-linked glycosylation sites. FGF19-FGFR1 is one of paired transcripts mediating the dialogues between extraembryonic membrane and endometrium. A functional binding ELISA assay was conducted to detect the interaction of Recombinant Human FGF19 Protein (rp145934) and recombinant human FGFR1, the EC50 for this effect is 0.16 μg/mL.    
  2. Recombinant Human PDGF-BB GMP Protein
      种属: 人(Human)    Accession #: P01127    
      表达系统: E. coli    蛋白标签: No tag     内毒素水平: <0.01 EU/μg    
      生物活性: Measured in a cell proliferation assay using NR6R‑3T3 mouse fibroblast cells. The ED50 for this effect is 1.5-6 ng/mL. The specific activity of recombinant human PDGF-BB is >7.5 x 10^5 IU/mg, which is calibrated against the human PDGF-BB WHO International Standard (NIBSC code: 94/728).
