DBCO-PEG5-NHS ester

DBCO-PEG4-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The hydrophilic PEG spacer increases the water solubility of the compound. Reagent grade, for research purpose.

TIGIT is an immune receptor present on some T cells and Natural Killer cells. TIGIT binds with high affinity to the poliovirus receptor (PVR) which causes increased secretion of IL10 and decreased secretion of IL12B and suppresses T cell activation by promoting the generation of mature immunoregulatory dendritic cells. Through the CD226/TIGIT-PVR pathway, TIGIT regulates T cell mediated immunity. In cancer, TIGIT and PD-1 have been shown to be over-expressed on tumor antigen-specific CD8+ T cells and CD8+ tumor infiltrating lymphocytes (TILs) from individuals with melanoma. Blockade of TIGIT and PD-1 led to increased cell proliferation, cytokine production, and degranulation of tumour antigen-specific CD8+ T cells and TIL CD8+ T cells. It can be considered an immune checkpoint.

Aflatoxin is the most common food toxin that is harmful to human and animal health. The most frequent aflatoxins are B1, B2, G1, and G2, which can affect the body through respiratory, mucosal, or cutaneous routes, causing an excessive inflammatory response. Aflatoxin can infect crops during their growing stages or even after they are harvested. It mainly targets the liver and can impair the effectiveness of immunization in children, increasing the risk of infection. Aflatoxin detection and quantification in food and feed is a critical part of food and feed safety concerns.
