Proteins and Peptides

Ready for use. Recombinant TEV protease with an N-terminal His-tag for simple removal from the cleavage reaction by immobilization on metal-affinity resins. TEV protease recognizes a linear epitope of the general form E-Xaa-Xaa-Y-Xaa-Q-(G/S), with cleavage occuring between Q and G or Q and S. The most commonly used sequence is ENLYFQG. This TEV protease contains a S219V...

Solid lyophilized powder. Soluble in water. Mitochondria-derived peptide (MDP), Promotes biosynthesis of the endogenous AMP analog AICAR and consequently AMP-activated protein kinase (AMPK), Induces cellular and systemic glucose uptake and improves insulin sensitivity. Shown to prevent diet-induced obesity (DIO) in mice, Potential anti-obesity and anti-aging compound.

Z-AEVD-FMK is an irreversible inhibitor of caspase-10 and related caspases. At 10 µM, it can prevent the initiation of Fas signaling by caspase-10 in Jurkat T lymphoma cells, preventing Bid cleavage into its active form, caspase cascade activation, and apoptosis.

Ac-LETD-AFC is a fluorogenic substrate that can be cleaved specifically by caspase-8. Caspase activity can be quantified by fluorescent detection of free AFC (also known as 7-amino-4-trifluoromethylcoumarin), which is excited at 400 nm and emits at 505 nm.

Active complex of human HDAC3 , GenBank Accession No. NM_003883, full length with C-terminal His tag, MW= 49.7 kDa, and human NCOR2 , amino acid 395- 489, GenBank Accession No. NM_006312, N-terminal GST tag, MW= 37.6 kDa, co-expressed in baculovirus expression system.

Active human PRMT3, GenBank Accession No. NM_005788, amino-acids 2-end, with N-terminal GST tag, MW=86 kDa, expressed in an E. coli expression system.

Tripeptidyl peptidase II (TPPII) is a serine peptidase of the subtilisin-type which removes tripeptides from the free NH2 terminus of oligopeptides. AAF-CMK is an irreversible inhibitor of TPPII commonly used at 10-100 µM. It does not significantly interfere with the chymotrypsin-like activity of the proteasome. AAF-CMK also inhibits bleomycin hydrolase and...

Macrophage Migration Inhibitory Factor (MIF) is a small, pro-inflammatory cytokine. MIF signaling is important in septic shock, arthritis, colitis, and cardiovascular diseases. MIF counteracts glucocorticoid signaling, which would otherwise inhibit inflammation. Secreted MIF binds to CD74 receptors, which then couple to CD44, during monocyte recruitment. In addition to CD44...

Ready for use. Recombinant TVMV protease with an N-terminal His-tag for simple removal from the cleavage reaction by immobilization on metal-affinity resins. TVMV protease cleaves the sequence ETVRQS, with cleavage occuring between Q and S residues with high specifity. It is mainly used for removing affinity tags from peptides. Affinity tags are often applied to facilitate...

Iberiotoxin, a peptide purified from venom of the scorpion B. tamulus, is a selective blocker of large-conductance calcium ion-activated potassium ion channels (BKCa). In single channel recordings, iberiotoxin can reversibly block outward currents mediated by BKCa in excised membrane patches from bovine aortic smooth muscle with an IC50 value of 250 pM. It is also a...

The heterochromatin protein 1 (HP1) family, which consists of three isoforms HP1alpha (CBX5), HP1beta (CBX1), and HP1gamma (CBX3) are chromatin-associated proteins involved in gene regulation and heterochromatin formation. CBX proteins have an N-terminal chromodomain, a C-terminal chromoshadow domain (CSD), and a hinge domain which connects the two. Extensive...
