Peptides

A fluorogenic substrate for caspase 3. The 7-amido-4-trifluoromethylcoumarin derivatives have better membrane permeability than the 7-amido-4-methylcoumarin derivatives.

A fluorogenic substrate for caspase 3, a protease that is rapidly activated when cells are exposed to apoptotic conditions and that cleaves poly(ADP-ribose) polymerase.

Cleavage of R110 peptides by caspases generates strongly fluorescent R110 that can be monitored fluorimetrically at 510-530 nm with excitation of 488 nm.This R110 substrate is specific for caspases 3 and 7.

The non-fluorescent R110 substrates generate the bright green fluorescent rhodamine 110 product that has Ex/Em = 494/521 nm, and can be easily detected with a FITC filter set. In general, R110 substrates are much more sensitive than the AMC-, AFC- or 4-nitroaniline-based substrates. This R110 substrate is used for...

3,3',5'-Triiodo-L-thyronine, also known as reverse T3 (rT3), is a thyroid hormone generated by deiodination of the prohormone thyroxine. It is about 1,000-fold less active at the thyroid hormone receptors TRalpha and TRbeta than 3,3',5-triiodo-L-thyronine (Cay-16028) and commonly described as inactive. However, high...

Angiotensin II is a peptide hormone known best as a vasoconstrictor with central roles in chronic hypertension, heart failure, and stroke. It is an octapeptide typically generated by the removal of two residues from angiotensin I by angiotensin-converting enzyme (ACE). Angiotensin II is a ligand for at least two...

Glucagon is a peptide hormone produced from proglucagon in pancreatic alpha cells that has a role in the regulation of glucose metabolism. Pulsatile application of glucagon to rat hepatocytes stimulates glucose production ex vivo. It also stimulates glucose output from perfused rat livers via increases in...

Tentoxin is a cyclic tetrapeptide first isolated from the plant pathogen A. alternata. It is an herbicide that inhibits chloroplast development, resulting in chlorotic tissue. Tentoxin is selectively phytotoxic, as it kills a number of important weeds at concentrations that have no effects on several important...

PI/PS (4:1, w/w) unilamellar vesicle, prepared with L-alpha-phosphatidylinositol (Liver, Bovine) (sodium salt) and L-alpha-phosphatidylserine (Brain, Porcine) (sodium salt). Lipid monolayer was formed by sonication. Application: Useful as a substrate for PI-3 kinase activity assays and other lipid kinases....

L-Leucyl-L-Leucine methyl ester (LLME) is a lysosomal condensation product that has been reported to be cytotoxic towards natural killer cells and CD4+ and CD8+ T lymphocytes without affecting helper T cells and B cells. It has also been shown to induce death of monocytes, polymorphonuclear leukocytes, and myeloid...
