DBCO-PEG5-NHS Ester is a DBCO-containing PEG linker containing NHS ester that can react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. PEG5 spacer increases the water solubility of compounds in aqueous media. DBCO is commonly used for copper-free Click Chemistry reaction. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) is a ready-to-use reagent with all the essential components for quantitative real-time PCR (qPCR) except primers and template. The master mix features high sensitivity and signal intensity as well as low background and better compatibility with cDNA templates derived directly from reverse transcription reaction mixture. The ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) contains hot-start Taq polymerase in an optimized buffer with dsDNA specific SYBR green fluorescent dye. This master mix allows for sensitive, precise amplification, real-time tracking of the amplification process, and simultaneous quantification for targeted DNA molecules. With inert smart blue contrast dye, the ExcelTaq™ 2X Q-PCR Master Mix (SYBR, no ROX) is ready-to-use and greatly reduces pipetting errors, while largely improving the reproducibility of the process. The ExcelTaq™ 2X Q-PCR Master Mix is also compatible with a ROX reference dye if recommended by the manufacturer of the qPCR system.
Features
High sensitivity and signal intensity
Smart blue contrast dye as a visual aid for reaction setup
Better compatibility for reverse transcription
Low background
Storage
Protected from light. Aliquot to avoid multiple freeze-thaw cycles. -20°C for 12 months

Norgen’s Saliva Exosome Collection and Preservation Kit is an all-in-one solution designed for 1) simple and non-invasive saliva collection; 2) preservation of exosomes in saliva samples at ambient temperature; and 3) isolation of high quality intact exosomes and exosomal RNA within a laboratory setting. The Saliva Exosome Collection, Preservation and Isolation Kit contains 50 Individual Saliva Exosome Collection and Preservation Devices. Each of the 50 individual Saliva Exosome Collection and Preservation Devices consists of 3 components:
Saliva Collection Funnel and Collection Tube that contains Norgen’s Preservative in a dried format
Collection Tube Cap
ID Label
Saliva samples are collected by spitting inside the Collection Funnel which has been assembled with the Collection Tube. After collecting the required volume of saliva the Collection Funnel is removed, the Collection Tube is securely capped with Collection Tube Cap. The collected saliva is mixed by gentle inversion for several times till the saliva colour changes into yellow. The Saliva Collection Tube is subsequently sent to the laboratory for the purification of intact exosomes and for the subsequent isolation and analysis of saliva exosomal RNA. The saliva exosomes in preserved samples are stable for 2 years at room temperature.
