I currently use mTeSR1. How difficult would it be to adapt my cells to the StemFlex Medium system?
This transition is very straightforward. We recommend at least a 2-passage transition into the StemFlex Medium system. Briefly, if you have cryopreserved cells previously cultured in the mTeSR1/Matrigel system, we recommend thawing the cells back into mTeSR1/Matrigel until fully recovered. Upon reaching ~70-85% confluency, passage using Versene solution and seed directly into the StemFlex Medium system.

Over 90 different mutations in the gene encoding copper/zinc superoxide dismutase (SOD1) cause approximately 2% of amyotrophic lateral sclerosis (ALS) cases by an unknown mechanism. We engineered 14 different human ALS-related SOD1 mutants and obtained high yields of biologically metallated proteins from an Sf21 insect cell expression system. Both the ... More

Fractalkine/CX3CL1 is a membrane-tethered chemokine that functions as a chemoattractant and adhesion protein by interacting with the receptor CX3CR1. To understand the molecular basis for the interaction, an extensive mutagenesis study of fractalkine's chemokine domain was undertaken. The results reveal a cluster of basic residues (Lys-8, Lys-15, Lys-37, Arg-45, and ... More
