N-(t-Boc-Aminooxy-PEG2)-N-bis(PEG3-propargyl) is a branched crosslinker molecule with two terminal propargyl groups and a t-Boc protected aminooxy group. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The protected amine can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

N-(Propargyl-PEG2)-DBCO-PEG3-N-Boc enables formation of triazole linkage with azide-bearing compound via copper catalyzed Click Chemistry. Under mild acidic conditions, t-Boc group can be removed to yield the free amine. The propargyl group can be linked to azide-containing biomolecules via Click Chemistry.

Advantages
The L-Malic Acid test kit is suitable for the measurement and analysis of L-malic acid in grapes, grape juice and wine using the MegaQuant™ colorimeter (measurement at 505 nm). Suitable for white and red wines at all stages of the winemaking process.
This kit is designed for the rapid spin column preparation of genomic DNA from 2 x 109 viable bacterial cells (between 0.5 and 1.0 mL of culture). This kit can be used for both Gram-negative and Gram-positive bacteria including Escherichia coli and Bacillus cereus. Purified genomic DNA is of an excellent quality and yield, and is fully compatible with restriction enzyme digestions, sequencing, PCR, qPCR and more. Also available in 96-well format for high throughput applications.
