Question about Apoptosis

... confused. Do perforins kill the cell, or does it send a signal and tell the cell to kill itself? And what is the difference between apoptosis and lysis? I'm a first year biology student, so if you can explain this is simple terms, that'd be great!

Cell lysis and Lowry assay for 2D electrophoresis

... some of my questions: 1)Can I use my 2D sample buffer: 8M Urea, 2% w/v CHAPS 50mM DTT 0.2% w/v100X Bio-Lyte ampholyte 0.002% w/v BPB for the cell lysis step as well? I am going to try both sonication and grinding techniques for cell lysis 2)Can I use Lowry assay if I use this 2D sample buffer ...

Re: Cell wall lysis

I'd try detergent. The pigments you are after are the mainly phycobiliproteins and the chlorophyll. http://en.wikipedia.org/wiki/Phycobilin

Cell wall lysis

Lysozyme, or concentrated lysozyme, at least, may help. Oddly enough, it is in your saliva, and it lysis cell walls. I don't actually know if it would work, so maybe someone will criticize me and provide a better answer.... but you could try it?
