I'm trying to use vitrogen collagen I as a stretchable substratum for seeding vascular smooth muscle cells (SMCs).
Right now, I'm using a protocol for mixing the gel which includes Vitrogen collagen stock, NaOH, and DMEM/FBS (The growth medium for my cells).
When I try stretching my collagen gel, the gel surface breaks or tears apart easily. If I want a stronger and more stretchable surface so that I can work with greater force of stretches, what should I do to make the gel stronger? Should I increase the relative proportion of Vitrogen Collagen solution?
