ProDots Recombinant Human KGF/FGF-7 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/lane of ProDots® Recombinant Human KGF/FGF-7 was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized with silver staining, showing a single band at 19 kDa.

ProDots® Recombinant Human KGF/FGF-7 stimulated cell proliferation of the 4MBr-5 rhesus monkey epithelial cell line. The ED50 for this effect is typically
6-60 ng/mL.
Background: KGF/FGF-7
KGF (keratinocyte growth factor), also known as FGF-7, is induced in mesenchymal cells by inflammation or tissue damage. It functions as a paracrine factor during wound healing by inducing the proliferation of nearby epithelial cells. KGF plays a role in kidney morphogenesis, hair follicle development, and keratinocyte differentiation. It signals only through the IIIb splice form of the tyrosine kinase receptor, FGF R2 (IIIb)/KGF R.

  • Alternate Names:
