Ubpbio SUC-LLVY-AMC, 25MG
Fluorescent Peptides/Protein Substrates – SUC-LLVY-AMC (UBPBio catalog# G1100, G1101) – Suc-LLVY-AMC is a fluorogenic substrate for the chymotrypsin – like activity of the 20S and 26S proteasomes. Working concentrations of this substrate is 50-200 µM. The released AMC can be detected by a fluorimeter or plate reader at excitation/emission wavelengths of 380 nm/460 nm, respectively. When used to determine proteasome activity in cell lysates, cell lysates that are pre-treated with a proteasome inhibitor such as MG132, PS341 or epoxomicin can be used to determine the fluorescence contributed by other cellular proteases that cleave this substrate. Readings from proteasome inhibitor-treated lysates should be subtracted.
Ubpbio BOC-LRR-AMC, 5MG
Fluorescent Peptides/Protein Substrates – BOC-LRR-AMC (UBPBio catalog# G3100, G3101) – Boc-LRR-AMC is a fluorogenic substrate for the trypsin – like activity of the 20S proteasome. Working concentrations of this substrate is 50-200 µM. The released AMC can be detected by a fluorimeter or plate reader at excitation/emission wavelengths of 380 nm/460 nm, respectively. When used to determine proteasome activity in cell lysates, cell lysates that are pre-treated with a proteasome inhibitor such as MG132, PS341 or epoxomicin can be used to determine the fluorescence contributed by other cellular proteases that cleave this substrate.

TARGETMOL CHEMICALS INC D-Luciferin potassium 100MG
Also available in 1 g, 10 mg, 50 mg, 500 mg and bulk. Please contact Fisher for quotes. D-Luciferin potassium (D-Luciferin K Salt) is a popular bioluminescent substrate of luciferase in the presence of ATP. Purity 99.13%
Gold Biotechnology Inc D-Luciferin, Potassium Salt (Proven and Published™) 2 x 1 g
Luciferin is a common bioluminescent reporter used for in vivo imaging of the expression of luciferase. This water soluble substrate for the firefly luciferase enzyme utilizes ATP and Mg2+ as cofactors to emit a characteristic yellow-green emission in the presence of oxygen, which shifts to red light in vivo at 37°C. Through the utilization of ATP, the reaction can be further used to indicate the presence of energy or life in order to function as a life-death stain.
Gold Biotechnology Inc Lysozyme, Egg White 5 g
Lysozyme is an enzyme capable of breaking down the bacterial cell wall, and is typically used to enhance protein extractions or nucleic acid extractions. It works by hydrolyzing the 1,4-β-linkages located between the N-acetylmuramic acid and the N-acetyl-D-glucosamine residues in peptidoglycan.
