N-(Propargyl-PEG2)-N-bis(PEG3-t-butyl ester) is a 3-arm PEG reagent with a propargyl groups and two t-butyl ester groups. The propargyl group can react with azides via copper catalyzed Click Chemistry reaction to yield a stable triazole linkage. The t-butyl ester groups can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction
Usages: For monitoring and detection of surface of equipment and personnel hygiene.
Advantage: 1.This series of products was filling at A level of environment, and final sterilization by Gamma ray irradiation, triple packaging insure sterility and long shelf life. 2.Each dish was marking label product name, batch number, expiration date .Information is available of traceability. 3.Inner additional desiccant, reducing formation of condensation water, while inner additional sterile paper and plastic bags for easier transfer and cultivation. 4.Triple packing dense bags to avoid the penetration of hydrogen peroxide; clean gas was filled as a buffer to reduce broken bags and dish in transit.. 5.This series of products is available to store at (2-25 ℃), shelf life of up to 6 months.
Storage: Store in a cool (2-25 ℃), dry place, away from bright light. Storage period of 6 months.
Norgen’s TaqMan 2x PCR Master Mix is a ready-to-use TaqMan 2x PCR Master Mix solution that contains a PCR internal control which can be detected by HEX/VIC channel in a real-time PCR machine. By detecting the internal control users can validate the DNA template quality, thereby preventing any false negatives in the PCR results. The user needs only to add template, target TaqMan primer/probe mix and water to set up the TaqMan real-time PCR.
PCR Control: TaqMan 2x PCR Master Mix contains PCR control primers/probe (HEX/VIC) and PCR control template. The PCR control reaction in the TaqMan 2x PCR Master Mix is optimized to not interfere with target amplification. The fluorescence of the target probe should not be HEX/VIC.
