RNA from feathers

... from feather in Google. Like that: http://jvdi.org/cgi/reprint/13/2/162.pdf and I am pretty sure that this method can be adapted for RNA (use the lysis conditions then do a trizol purification instead of the phenol choloroform): http://jvdi.org/cgi/reprint/13/2/162.pdf

Problems related to Microsome Preparation

... as I am troulbed by the absence of results!!! I used LCC6MDR to take microsomes from fragement of plasma membrane. I lysed the cells by lysis buffer first and then centrifuged it at 500g for 10 min in cold room to take supernatant use another centrifugation at 5000g for 10 min in cold ...

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!
