Identification of human milk kappa-casein on polyacrylamide gels by differential staining with Ethyl-Stains-all and chymosin sensitivity.

Rapid Coomassie blue staining and destaining of polyacrylamide gels.

Silver-staining of proteins in polyacrylamide gels: a general overview.

On the basis of the physico-chemical principles underlying silver-staining of proteins, which are recalled in this paper, several methods of silver-staining of proteins after SDS electrophoresis in polyacrylamide gels or isoelectric focusing were tested. The most valuable protocols are presented in this report, including standard methods for unsupported gels and new methods devised for thin (0....

Agarose overlays allow simplified staining of polyacrylamide gels.

Laser scanners from Molecular Dynamics (Sunnyvale, CA, USA) or Hitachi Scientific Instruments (Mountain View, CA, USA) are being used increasingly to detect DNA in polyacrylamide gels. The standard technique for visualizing DNA is to separate the plates of a gel and pour a diluted nucleic acid stain such as ethidium bromide or SYBR Green I [from Molecular Probes (Eugene, OR, USA); also markete...

Visible fluorescent detection of proteins in polyacrylamide gels without staining.

2,2,2-Trichloroethanol (TCE) incorporated into polyacrylamide gels before polymerization provides fluorescent visible detection of proteins in less than 5min of total processing time. The tryptophans in proteins undergo an ultraviolet light-induced reaction with trihalocompounds to produce fluorescence in the visible range so that the protein bands can be visualized on a 300-nm transilluminator...

reverse staining method of polyacrylamide gels by imidazole-zinc salts for

the human papillomavirus l1 major capsid protein (hpv l1), the basis of the current vaccines, self-assembles into virus-like particles (vlps). herein, we describe the expression and purification of recombinant hpv16 l1 in e. coli system. the l1 protein was generated in a fused form using an inducible expression system. the recombinant gst-l1 fusion protein migrated as a 82 kda protein in sds-pa...
