Supplier: ProSci Inc.

IDO catalyzes the first and rate-limiting step in the main pathway of human tryptophan catabolism, the kynurenine pathway. Proinflammatory mediators, such as endotoxin and IFN-gamma induce the expression of IDO in several tissues. IDO-dependent suppression of T-cell responses might function as natural immunoregulatory mechanism. Physiological IDO activity has been implicated in T-cell tolerance to tumors, dysfunctional selftolerance in non-obese diabetic (NOD) mice, and as a protective negative regulator in autoimmune disorders.

Supplier: Bioss

Component of the Mediator complex, a coactivator involved in regulated gene transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors. Binds to and activates cyclin-dependent kinase CDK8 that phosphorylates the CTD (C-terminal domain) of the large subunit of RNA polymerase II (RNAp II), which may inhibit the formation of a transcription initiation complex.

Supplier: Avantor

Avantor® ACE® UltraCore SuperPhenylHexyl solid-core (core-shell) particle columns are ideal for demanding MS work offering improved MS signal intensity and maximum MS response. These stainless steel columns combine high efficiency separations with low column back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and effectively eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability.

Supplier: Thermo Fisher Scientific

The Hydrophilic Interaction Liquid Chromatography (HILIC) technique offers complementary selectivity to reversed phase. With the ability to retain highly polar and hydrophilic compounds, these columns have been developed to aid the analysis of compounds that are traditionally difficult to retain using conventional C18 columns.

Bungarotoxins are venom toxins from the many-banded krait (Bungarus Multicinctus), which inhibit neurotransmission at the neuromuscular junction. Alpha-bungarotoxin is a potent inhibitor for the motor endplate acetylcholine receptor (Kd = 1 nM to 1 pM). Beta-bungarotoxin contains a small subunit that blocks voltage-gated K+ channels on the presynaptic membranes, and a large subunit that has phospholipase A2 activity. Fluorescent conjugates of alpha-bungarotoxin can be used to label acetylcholine receptors in skeletal muscle endplates.
