背景介绍 L-Trp is an essential amino acid necessary for protein synthesis in mammalian cells, and the L-Trp to Kyn pathway is firmly established as a key regulator of innate and adaptive immunity. Catabolism of L-Trp to Kyn maintains an immunosuppressive microenvironment by starving immune cells of L-Trp and releasing degradation products of L -Trp that have immunosuppressive functions. IDO2 is upregulated in many tumors, providing cancer cells with an avenue for immune evasion. 产品介绍 The IDO2 Cellular Activity QuickDetect™ Supplements are designed to complement the hIDO2-HEK293 Recombinant Cell Line (BPS Cat. #60532) or other IDO2- expressing cell lines. This kit contains the cell culture medium supplements necessary for activation of IDO2 and for the analysis and detection of indoleamine 2,3 dioxygenase (IDO2)- catalyzed conversion of L-tryptophan (L-Trp) to Kynurenine (Kyn). The supplements and the detection reagents, when used as described, allow for indirect measurement of Kyn levels by analyzing absorption at 480 nm.

询价背景介绍 The TLR family plays a fundamental role in pathogen recognition and activation of innate immunity. TLR8 is an endosomal receptor that recognizes single stranded RNA (ssRNA), and can recognize ssRNA viruses such as Influenza, HIV and HCV. TLR8 binding to the viral RNA recruits MyD88 and leads to activation of the transcription factor NF-κB and an antiviral response. Human TLR8 is functional but murine TLR8 is non-functional because it lacks five amino acids. 产品介绍 Recombinant HEK293 cell expressing firefly luciferase gene under the control of NFκB response elements with constitutive expression of human TLR8 (Toll-like receptor 8, also known as CD288, a member of the toll-like receptor (TLR) family (GenBank Accession No. NM_138636).

背景介绍 Iodine transport is essential for the production of thyroid hormone (T4). Sodium Iodide Symporter SLC5A5 (NIS) is a sodium-dependent transporter of iodide into thyroid follicular cells and other peripheral tissues to support T4 synthesis [1]. Lack of iodide transport can result in hypothyroidism and can manifest itself in several disease states like goiter formation and weight gain. SLC5A5 also plays an important role in hyperthyroidism (an excessive production of T4). Expression and activity of SCL5A5 is altered in several forms of cancer. Inhibitors of SLC5A5 have potential therapeutic benefit for the regulation of iodine overload induced by amiodarone or other thyromimetics that can result in hyperthyroidism [2]. 产品介绍 Stable recombinant HEK293 cell line expressing human SLC5A5 (UniProt # Q92911) with a C-terminal FLAG- tag. SLC5A5 is a sodium-dependent iodide transporter and is a member of the sodium glucose co-transporter family. The expression of SLC5A5 is confirmed by Western blotting. This cell line can be used to evaluate agents that may affect iodide transport.
询价背景介绍 Calcium-activated chloride channels (CaCCs) are involved in a variety of physiological functions including smooth muscle contraction and olfaction. TMEM16B (ANO2) has been identified as a CaCC that is activated by intracellular Ca2+ and Ca2+-mobilizing stimuli. It has eight putative transmembrane segments and is permeable to monovalent anions. 产品介绍 Recombinant HEK293 cell line expressing human TMEM16B (transmembrane protein 16B, also called as anoctamin 2, calcium-activated chloride channel (ANO2), accession number NM_001278596).
询价背景介绍 TRPM2 channel belongs to the transient receptor potential channel (TRP) superfamily which is divided into seven main subfamilies. TRPM2 channel is a nonselective, calcium-permeable cation channel highly expressed in the brain, vascular smooth muscle, endothelial cells and immune cells. It is activated by oxidative stressors such as hydrogen peroxide, cyclic ADP ribose, and NADP, leading to an increase in the intracellular free calcium concentration and cell death. TRPM2 is a potential drug target in a variety of human diseases, including cardiovascular and neurodegenerative diseases. 产品介绍 Stable, recombinant HEK293 cell line expressing tetracycline-inducible human TRPM2 (transient receptor potential cation channel, subfamily M, member 2, accession number NM_003307).
询价背景介绍 IKCA1 is part of a potentially heterotetrameric voltage-independent potassium channel that is activated by intracellular calcium. Activation is followed by membrane hyperpolarization, which promotes calcium influx. The encoded protein may be part of the predominant calcium-activated potassium channel in T-lymphocytes. 产品介绍 Stable, recombinant HEK293 cell line expressing human IKCA1, also known as KCNN4 (Intermediate conductance calcium-activated potassium channel protein 4), IK1, hKCa4, and hSK4, GenBank Accession No. NM_002250.
