Horizontal Spread Assay

Horizontal Spread Assay (on 10T1/2 mouse fibroblasts) 10T1/2 fibroblasts work well for this assay because they grow well in DME 10% IFS, are infectable with high efficiency, and can be killed off rather quickly with standard drugs.  Also, for routine passaging, the cells can also be split sparsely (a 1:10 or 1:15 split is usually […]

Human 3D Collagen Morphogenesis Assay

1) Freshly dissociate organoids into single cells and then seed 500K in 500µl/well in a 48 well non-adherent plate with protamine sulfate with virus at MOI 3 for infection overnight.  (Patty and I have both stopped spin infecting the cells. This method seems to produce less cell death. I need to infect roughly 2x the […]
