How to convince suspension cells to adhere more tightly?
I'm developing a cell-based assay in 96-well plates that requires adherent cells, as they need to be washed at least twice during the protocol. I'm using in-house strains of HT1080 cells (some ...

Is there a photobleaching-resistant, cell-permeant viability stain in the far red part of the spectrum?
I am looking for a live-cell–impermeable dye for viability. (The cells cannot be permeabilized and fixed in this experiment.) I would prefer with excitation and emission spectra similar to Cy5, but I ...

How do different tissue culture matrices affect background in fluorescent microscopy?
In response to my previous question, I've been reading up a little bit on poly-D-lysine, Collagen I, Collagen IV, laminin, and other tissue culture coatings that promote cell adhesion. I've always ...
