Protocol

The amount of lysis buffer should be empirically determined for each cell type to ensure efficient lysis as well as an optimal final concentration of protein in the lysate Using a cell scraper or silicone spatula scrape the cells and transfer the lysate to a 15 ml conical Incubate the lysate on ice for 15 minutes Sonicate the lysate (Branson Digital Sonifier set at 50% amplitude) three

Choosing The Right Lysis Buffer

Nuclear/mitochondria proteins RIPA is the preferred choice here However fractions protocols are often used to increase the concentration of the desired protein Cytoplasmic proteins A Tris-HCl lysis sometimes shows advantages over RIPA buffer Optimal conditions should be tested for the protein of interest Don't forget your inhibitors

Bacterial Cell Lysis Buffer

Bacterial Cell Lysis Buffer INTRODUCTION The Bacterial Lysis kit has been developed for the extraction of soluble proteins and inclusion bodies from bacterial cells It is a proprietary improvement on the lysozyme based lysis which allows extraction of soluble proteins and concurrent removal of nucleic acids (DNA RNA) released during cell lysis The lysis eliminates viscosity build-up

Purification and Identification of Recombinant GFP

washes in mid-salt elute unbound and weakly interacting proteins Finally incubation with low-salt TE buffer restores the normal structure of GFP and releases the protein from the resin The eluted protein is transferred to a sep-arate tube and its characteristic fluorescence is detected by exposure to long-wavelength UV light ("black light") • Part B provides a technique whereby
