Background
The green fluorescent protein (GFP) is a protein that exhibit bright green fluorescence when exposed to blue light. The protein is in the shape of a cylinder, comprising 11 strands of β-sheet with an α-helix inside and short helical segments on the ends of the cylinder. Its ability to generate a highly visible, efficiently emitting internal fluorophore is both intrinsically fascinating and tremendously valuable. The green-fluorescent protein (GFP) of the jellyfish Aequorea victoria has long been used as a universal reporter in a broad range of heterologous living cells and organisms. GFP has become well established as a marker of gene expression and protein targeting in intact cells and organisms.

Beta-Lactamase (TEM-1) Protein

TEM-1 beta-lactamase is the most widespread enzyme to confer beta-lactam antibiotic resistance to gram-negative bacteria. It is a monomeric protein that requires no metals or cofactors for activity. TEM-1 beta-lactamase efficiently hydrolyzes most penicillin and cephalosporin substrates, including nitrocefin and fluorescent derivates. This protein is intended to be used as a positive control for enzyme-dependent substrate hydrolysis and for use on immunoblots. Other uses include kinetic studies with novel substrates or identification of inhibitors of beta-lactamase as part of an antimicrobial program.
