Propargyl-PEG8-acid has an alkyne group and an acid group. The acid group can derivatize amine-containing molecules in the presence of activators such as EDC or HATU. The alkyne group can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Programmed Death 1 (PD-1) is a member of the CD28/CTLA-4 family of T-cell regulators, expressed as a co-receptor on the surface of activated T-cells, B-cells, and macrophages. New studies have suggested that the PD-1/PD-L1 signaling pathway may be linked to anti-tumor immunity, as PD-L1 has been shown to induce apoptosis of activated T cells or inhibit activity of cytotoxic T cells. In comparison to CD10 and Bcl-6, PD-1 is expressed by fewer B cells and has therefore been considered a more specific and useful diagnostic marker for angioimmunoblastic T-cell lymphoma. Therapies targeted toward the PD-1 receptor have shown remarkable clinical responses in patients with various types of cancer, including non–small-cell lung cancer, melanoma, and renal-cell cancer.

The hydrogen peroxide Assay Kit provides a simple robust method for the measurement of hydrogen peroxide. This kit utilizes a highly sensitive Megaplex Red probe which in the presence of horseradish peroxidase (HRP), allows for the measurement of H2O2 in a sample. Upon oxidation of the probe by HRP, a coloured product (resorufin) is formed that can be measured in fluorescence mode using excitation in the range 530-560 nm and emission at ~ 590 nm or colourimetrically at 570 nm. The excitation and emission maxima of Megaplex Red are 571 nm and 585 nm respectively.

DBCO-PEG4-PABA is an analog of DBCO-Acid with PEG linker and a 4-Aminobenzoic acid (PABA) group. The DBCO groups is commonly used for copper-free Click Chemistry reactions due to its strain promoted high energy. The hydrophilic PEG chain allows for increased water solubility. Reagent grade, for research use only.
