71183 NucBuster Protein Extraction Kit
Rapid and convenient extraction of nuclear proteins
The NucBuster™ Protein Extraction Kit (Bruggink 2002) provides an alternative to the time intensive and cumbersome traditional methods for preparing nuclear extracts from mammalian cells. Time consuming traditional methods (up to 7 hours), based on a procedure originally described by Dignam et al. (1983), includes suspending cells in hypotonic solution, Dounce homogenization, centrifugation, and dialysis. The NucBuster Kit protocol is rapid and allows for the easy processing of multiple samples. The entire procedure from start to finish yields ready-to-use nuclear extract within 30 minutes. The composition of gentle detergents and salt in the final NucBuster extract is directly compatible with electrophoretic mobility shift assays (EMSA).
The NucBuster protocol is based on two proprietary detergent-based solutions, NucBuster Extraction Reagent 1, optimized for cell lysis and removal of cytoplasmic components, and NucBusterExtraction Reagent 2, optimized for extraction of nuclear proteins. In addition, NucBuster extract is free of the 'stickiness' associated with release of genomic DNA, a problem associated with some traditional methods. No Dounce homogenization is required and there is no need for dialysis. The entire procedure is performed in a single microcentrifuge tube and requires only a vortex mixer and microcentrifuge. The kit provides enough reagents for 100 preparations of nuclear extract from 1 x 107 to 5 x 107 cells and the protocol is scalable.
