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

Benefits  

• 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.

Background: IL-10

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.
