Proteins and Peptides

Human transferrin is encoded by the TF gene and is an iron-binding blood plasma glycoprotein that controls the level of free iron in biological fluids. Human transferrin binds iron very tightly but reversibly. Human transferrin is the most important iron pool in mammals. Human transferrin has a molecular weight of...

A fluorogenic caspase-8/granzyme B substrate containing the acetyl (Ac) moiety.

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...

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.

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....

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...

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...

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...

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...

CBX2 is a component of the polycomb repressive complex 1 and represses protein expression. The chromodomain regions of CBX2 recognizes histone H3 trimethyl lysine 9 (H3K9me3) or trimethyl lysine 27 (H3K27me3). CBX2 knock-out mice have impaired spleen formation, T cell expansion, and inactivation of the X chromosome,...
