Description: Apoptosis, or programmed cell death, occurs during normal cellular differentiation and development of multicellular organism. It is induced by certain cytokines including TNF and Fas ligand in the TNF family through their death domain containing receptors. TRAIL/Apo2L is a new member of the TNF family which is expressed in a variety of human tissues. Similar to TNF and Fas ligand, TRAIL induces apoptosis and NF-κB activation in many tissues and cells. Its receptors include the death domain containing proteins DR4 and DR5, both of which mediate TRAIL induced cell death. Two decoy receptors, DcR1 and DcR2, have also been identified. Both of these proteins contain an extracellular TRAIL binding domain but lack intracellular signaling domains. Overexpression of either DcR1 or DcR2 attenuates TRAIL-induced apoptosis.;;For images please see PDF data sheet

Description: Thymic stromal lymphopoietin (TSLP) has recently been identified as an important factor capable of driving dendritic cell maturation and activation. TSLP is a four-helix-bundle cytokine that is expressed mainly by barrier epithelial cells and is a potent activator of several cell types such as myeloid dendritic cells. TSLP is involved in the positive selection of regulatory T cells, maintenance of peripheral CD4+ T cell homeostasis and the induction of CD4+ T cell-mediated allergic reaction. TSLP is also capable of supporting the growth of fetal liver and adult B cell progenitors and their differentiation to the IgM-positive stage of B cell development. Amino acid sequence analysis has shown poor homology between human and mouse TSLP although they exhibit similar biological functions and are expressed in similar tissues. The TSLP receptor (TSLP-R) will bind TSLP in a low-affinity fashion in transfected cells; co-transfection with IL-7R cDNA results in high-affinity binding and a functional heteromeric complex. This heteromeric receptor requires stat5 for TSLP-mediated signal transduction and is inhibited by SOCS1. Despite their predicted molecular weight, TSLP and TSLP-R often migrate at a higher molecular weight in SDS-PAGE. Antibody #4209 recognizes only mouse protein; #4025 recognizes both mouse and rat proteins. Antibodies #4021 and #4207 are specific for human proteins.;;For images please see PDF data sheet

Description: Novel Coronavirus (2019-nCoV) Real Time Multiplex RT-PCR Kit is used for the qualitative detection of a novel coronavirus, which was identified in 2019 at Wuhan City, Hubei Province, China, in upper respiratory tract specimens (nasopharyngeal extracts, deep cough sputum, etc.) and lower respiratory tract specimens (alveoli irrigation fluid, etc.) by real time PCR systems. It detects N gene, E gene and RdRp gene of 2019-nCoV. RR-0479-02 has been also approverd by CFDA for emergency use and is WHO standard.
