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.

1 μg/lane of ProDots® Recombinant Human IL-10 was resolved with SDS-PAGE under reducing (R) and non-reducing (NR) conditions and visualized by silver staining, showing major bands at 18 kDa and 16 kDa, respectively.
Interleukin-10 functions as an anti-inflammatory cytokine by inhibiting the expansion and activation of Th1 cells and Th17 cells and by promoting the development of M2 macrophages and regulatory T cells (Treg). Within a tumor microrenvironment, however, IL-10 can inhibit the expansion of both Treg and myeloid-derived suppressor cells (MDSC). IL-10 exerts protective effects including limiting tissue damage in arthritic inflammation and promoting muscle regeneration after injury, but it also contributes to the persistence of viral infections. IL-10 signals through a receptor complex composed of IL-10 R alpha and IL-10 R beta. IL-10 R beta additionally associates with IL-20 R alpha, IL-22 R alpha 1, or IL-28 R alpha to form the receptor complexes for IL-22, IL-26, IL-28, and IL-29.
