Description: Microcystins are a group of cyclic heptapeptide hepatotoxins produced by a number of cyanobacterial genera. The most notable of which, and namesake, is the widespread genus Microcystis. Structurally, all microcystins consist of the generalized structure cyclo(-D-Ala1-X2-D-MeAsp3-Y4-Adda5-D-Glu6-Mdha7-). X and Y are variable L-amino acids, D-MeAsp is D-erythro-β-methylaspartic acid and Mdha is N-methyldehydroalanine. Adda is the cyanobacteria unique C20 β-amino acid 3-amino-9-methoxy-2,6,8-trimethyl-10-phenyl-deca-4,6-dienoic acid. Substitutions of the variable L-amino acids at positions 2 and 4 give rise to at least 21 known primary microcystin analogs and alterations in the other constituent amino acids result in more than 90 reported mycrocystins to date.

Description: Sensitive fluorogenic substrate for TACE (TNFalpha converting enzyme, ADAM17). Also cleaved by ADAM10 and likely other ADAMs and MMPs. The kcat/Km of TACE for this substrate is 7-fold higher than for the same peptide with the Mca-Dpa fluorophore-quencher pair. FAM fluorescence is quenched by the TAMRA group until cleavage separates them. Ex.: 485 nm, Em.: 535 nm, although the following Ex/Em can also be used: 490,494/515,520 nm. This substrate is useful for inhibitor screening, kinetic analysis, and cellular activity assay.
UOM: 1 * 1 EA

Fournisseur: Merck
Description: N-Succinimidyloxycarbonylmethyl tris(2,4,6-trimethoxyphenyl)phosphonium bromide (TMPP-Ac-OSu) is an acylating reagent, and is generally used for the selective derivatization of N-terminal a-amino group of peptide.
UOM: 1 * 50 mg

Fournisseur: ENZO LIFE SCIENCES
Description: Quenched fluorogenic substrate for cathepsin D (kcat/Km=1,09×10 M-1s-1) and cathepsin E (kcat/Km=1,56×10 M-1s-1). Mca fluorescence is quenched by the Dnp group until cleavage separates them. Activity of the two enzymes on this substrate can be distinguished by the use of Ascaris pepsin inhibitor, which inhibits cathepsin E, but not cathepsin D. This substrate is also cleaved by MMP-2, MMP-3, MMP-9, but not MMP-1 nor MMP-13. This substrate is useful for inhibitor screening and kinetic analysis. Ex.: 320-340 nm, Em.: 393-420 nm. Mca-Pro-Leu-OH (BML-P127) can be used to calibrate for Mca fluorescence.

Fournisseur: G-Biosciences
Description: Ellman's reagent is a versatile, water-soluble compound for quantifying free sulfhydryl groups in solution. It reacts with a free sulfhydryl group to yield a mixed disulfide and 2-nitro-5-thiobenzoic acid (NTB), a measurable yellow colored product at 412nm.
Ellman's reagent is very useful as a free sulfhydryl assay reagent due to its high specificity for -SH groups at neutral pH, high molar extinction coefficient and short reaction time.
UOM: 1 * 5 g

Fournisseur: TCI
Description: Application: SILREST (10-50 μL) is directly injected into GC at 150-250 °C of the column temperature. The baseline of the recorder normally stabilizes within several minutes. If not, injection of SILREST is repeated until the baseline stabilizes. Note: SILREST cannot be used for glycerin, polyethylene glycol, other liquid phases having activated hydrogen such as hydroxyl group, thiol group, carboxyl group, amino group, imino group.
