ProDots Recombinant Human VEGF 165 Protein

Supplied as ready-to-use 5 ug protein balls

Pre-aliquoted, lyophilized protein dots for use in cell culture medium

  • Rolls out of bottle for easy cell culture medium preparation
  • Eliminates time spent aliquoting
  • One protein dot can be used to make 500 mL of 10 ng/mL cell culture medium

Why use ProDots™ Proteins Instead of Standard Lyophilized Protein?

ProDots® proteins are designed to reduce cell culture media preparation time while ensuring optimal protein recovery and bioactivity. Unlike standard lyophilized protein, which is shipped as a diffuse residue within a vial, ProDots® proteins are neatly bundled into the shape of a ball. In this form ProDots® proteins can be rolled directly into cell culture media. ProDots® proteins rehydrate instantly in media to maximize the recovery of purchased protein and to reliably reconstitute it at a desired concentration for use in cell culture media. ProDots® proteins can be conveniently stored at room temperature where they will remain stable for 6 months or at 4 ºC where they will remain stable for 12 months. The accessible storage and high stability of ProDots® proteins makes them ideal for quick and easy preparation of cell culture media.

What are ProDots® Proteins?

ProDots® proteins are R&D Systems industry-leading quality, highly bioactive proteins packaged into easy-to-use lyophilized “dots”. Designed to be stable at 4 ºC and to dissolve instantly, ProDots® proteins can be rolled into cell culture media to quickly produce media with a desired working protein concentration.

Data Images
1 μg/mL of ProDots® Recombinant Human VEGF165 was resolved by SDS-PAGE with silver staining, under reducing (R) and non-reducing (NR) conditions, showing major bands at 20-22 kDa and 39-42 kDa, respectively. Multiple bands in the gel are due to glycosylation.   
ProDots® VEGF165 stimulates proliferation in HUVEC human umbilical endothelial cells. The ED50 is typically 1.0-6.0 ng/mL.
Background: VEGF
VEGF (Vascular endothelial growth factor) is a potent mediator of both angiogenesis and vasculogenesis in the fetus and adult. It is required for regulating the proliferation, migration, and survival of embryonic endothelial cells and during wound healing and the female reproductive cycle in adults. Pathologically, it is involved in tumor development and tumor vascular leakage. VEGF binds to VEGF R1/Flt-1, VEGF R2/Flk-1/KDR, and Neuropilin-1. Multiple forms of VEGF are generated by alternative splicing and proteolysis.
