Overview

Recombinant Human VEGF121 is a biologically active, non-heparin-binding isoform of Vascular Endothelial Growth Factor A. This homodimeric glycoprotein plays a central role in angiogenesis and endothelial cell function by stimulating mitogenesis via VEGF receptors. VEGF121, lacking the heparin-binding domain of larger isoforms, is fully soluble and particularly useful for controlled in vitro vascular studies. Expressed in E. coli and highly purified, this recombinant cytokine supports a wide variety of vascular biology, tissue regeneration, and cancer-related applications.

Key Features and Benefits

  • Validated Bioactivity: Promotes dose-dependent HUVEC proliferation (ED₅₀ ≈ 10 ng/mL).
  • Soluble Isoform: VEGF121 does not bind heparin, offering consistent activity in solution-phase assays.
  • High Purity, Low Endotoxin: >95% purity by SDS-PAGE; endotoxin level <1 EU/µg.
  • Stable Lyophilized Format: Long shelf-life and flexible storage options.
  • Reliable Expression: Recombinant production in E. coli enables scalable research-grade consistency.

Reconstitution Instructions

  1. Briefly centrifuge vial to collect contents.
  2. Reconstitute with sterile distilled water to ≥ 0.1 mg/mL.
  3. Gently swirl to dissolve—do not vortex.
  4. For downstream use, further dilution in compatible buffer or media is recommended.
  5. Filter sterilization may be required based on application.

Quality Control (QC)

  • Purity validated by SDS-PAGE
  • Endotoxin tested via LAL method
  • Activity confirmed through HUVEC proliferation assay
