ProDots Recombinant Human G-CSF 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 G-CSF was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized with silver staining, showing a single band at approximately 18 kDa.

ProDots® Recombinant Human G-CSF stimulated cell proliferation of the NFS-60 mouse myelogenous leukemia lymphoblast cell line. The ED50 for this effect is typically
10-60 pg/mL.
Background: G-CSF
G-CSF (granulocyte-colony stimulating factor) is a secreted glycoprotein that regulates the proliferation, differentiation, and activation of neutrophilic granulocyte lineage cells. It also enhances M-CSF induced monocyte differentiation and the proliferation of Th2-inducing dendritic cells. G-CSF promotes the development of T cell immune tolerance as well as tissue recovery following myocardial infarction and cerebral ischemia. It signals through G-CSF R/CD114 on monocytes, neutrophils, megakaryocytes, platelets, myeloid progenitors, trophoblasts and placenta, endothelial cells, and various tumor cell types. Mutations in G-CSF R are associated with congenital neutropenia.
