#143418 Nocodazole-induced apoptosis

Posted bob1 on 15 October 2012 - 11:30 AM

Here's what my go-to drug list has to say:

Quote

Nocodazole
Has specific antimicrotubular activity for mammalian cells in culture. Promotes
microtubule depolymerization. Nanomolar concentrations alter microtubule dy-
namics and interfere with fibroblast locomotion without affecting polymer levels.
Arrests cells in mitosis.
Soluble in: DMSO
Stock concentration: 10 to 30 mM (store at room temperature)
Working concentration: 50 nM (low concentrations) to 30 µM (for effective mi-
crotubule depolymerization)
Duration of incubation: For rapid depolymerization of microtubules, preincubate
cells on ice with nocodazole for 15 min; use up to 24 hr.

Note: the actual concentration you should use will depend on the cell line and should be titrated before use.


#131249 Filamentous phage infection

Posted BioMiha on 19 March 2012 - 12:21 AM

If your multiplicity of infection (MOI) is low, you can be fairly certain according to the Poisson distribution that you will have only one phage per cell. If MOI is high then more phage can infect at once. Helper phage cannot replicate, but are added at a high MOI to ensure rescue of all displaying phage.
