ProDots Recombinant Human GM-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 GM-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 14 kDa.
ProDots Recombinant Human GM-CSF stimulates cell proliferation of the TF-1 human erythroleukemic cell line. The ED50 for this effect is typically 6-30 pg/mL
Background: GM-CSF
GM-CSF (Granulocyte-Macrophage Colony Stimulating Factor) induces the development of monocytes, neutrophils, eosinophils, and myeloid and dermal dendritic cells. It also acts as a neutrophil and dendritic cell chemoattractant. GM-CSF promotes Th1 and Th17 cell mediated autoimmune inflammation as well as the inflammatory activation of dendritic cells, microglia, alveolar macrophages, and eosinophils. In addition, it cooperates with G-CSF in promoting tumor cell proliferation and invasion. GM-CSF signals through a receptor complex composed of GM-CSF R alpha and the Common beta Chain (beta c) with Syndecan-2 as a potential co-receptor. The beta c subunit is shared by the receptor complexes for IL-3 and IL-5.
