Process Flow Update

Scope: The purpose of this experiment was to determine which conditions are best for differentiating adipose cells into endothelial cells  and formation of networks. ADSCs were used for this experiment, variables included media and matrices. Geltrex and collagen were used as matrices for the cells, the bottom of the plate was used as the control….

We’ve been wondering for some time just how the thinness of our membrane will affect the concentration polarization behavior of solutes. Because solutes with sieving coefficients less than 1 are (by definition) moving slower than the solvent around them, in the area before the membrane their concentration increases. In the case of proteins, this so-called…

This data is from about a month ago and it something that Jim has been asking me to put up, so here it finally is. When Tejas runs his experiments, he usually leaves me the last mL of blood that he has from his draw in case I want to do anything with it. One…

I’ve updated by 3D separations figure by using actual DLS sizes rather than the dimensions roughly obtained from crystal structures.  I have run into a snag with reporting the data however – use sizes by intensity or sizes by number.  The difference is due to the fact that the raw DLS data is from intensity,…

One of the ongoing efforts with endothelial cell culture on pnc-Si is to confirm that the holes in these cells are actually vacuoles.  In my last post, I tried to do this with FITC-Dextran and TMRIA with indefinite results.  I ordered some 5-6-carboxytetramethylrhodamine (TAMRA, C-300 from Invitrogen) to do this test again.  This rhodamine dye…

Since we last discovered our polyurethane acrylate (PUA) has a shelf life (described here) and received a new solution of PUA, we have been trying to replicate the results that we had before. Unfortunately, we have realized that this is much easier said than done. What we have found is the specific dilution of PUA…
