Mechanism of Saponin in laboratory use?

... useful. As far as I know, it's used to get stuff inside the cells, but I can't figure out whether it's a regular detergent or some kind of vesicle forming compound that 'transports' whatever it is you want, inside. Anyone has a clue?

Re: Protein expression but no mRNA

... than expressed in the cultured primary cells? I doubt that would be the case because on fusion of the endosome with a lysosome the proteins in the vesicle are usually degraded by the lysosomal enzymes. For the protein to enter using endosomes, it would have to either resist proteolytic degradation ...

... and the presence of the electrondense ferritin stain, and examined using the electron microscope. Both EGF and HRP were present in small vesicles with an internal radius of 20 nm but EGF was very commonly detected whereas the HRP was rarely detected. The rates of EGF and HRP uptake were ...

Re: Campbell and Reece 8th edition

... I know that the signal receptors would be on the outside of the plasma membrane but I wonder why it would be on the INSIDE of the ER membrane, vesicle and Golgi body- I mean how would the signal reach the receptor if they are on the INSIDE??? Or are the ER membrane, vesicle and Golgi body something ...

Re: Campbell and Reece 8th edition

it will also be on the inside of the ER membrane, it will also be on the inside of the vesicle and Golgi membrane, but it will be on the outside of the plasma membrane after exocytosis occurs. Think about how are the membranes oriented ;) http://www-bioc.rice.edu/bios576/membrane/Membrane_Fusion.jpg ...
