Validation Data Gallery

• 

  Purity of recombinant human FLT3 Ligand was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

• 

  Recombinant human FLT3 (HZ-1151) Ligand stimulates dose-dependent proliferation of the human acute myeloid leukemia cell line (OCI-AML5). Viable cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. OCI-AML5 cells were treated with increasing concentrations of recombinant human FLT3 Ligand for 72 hours. The EC50 was determined using a 4- parameter non-linear regression model. The EC50 values range is 0.4-3 ng/mL.

Background

FMS-related tyrosine kinase 3 ligand (FLT3 Ligand) is a growth factor that regulates proliferation of early hematopoietic cells. FLT3 Ligand binds to cells expressing the tyrosine kinase receptor FLT3. FLT3 Ligand by itself does not stimulate proliferation of early hematopoietic cells, but synergizes with other CSFs and interleukins to induce growth and differentiation (PMID: 8590775; 7544638; 12176867).
