N-(Acid-PEG4)-N-bis(PEG4-Propargyl) is a trifunctional PEG linker that combines a t-butyl ester with two terminal alkynes. The alkynes can be applied in copper-click chemistry with azides to form stable triazole linkages with a target molecule, while the acid can be reacted with amines or alcohols to form stable amides or esters.

Isothermal Nucleic Acid Principle Summary
The kit is based on rapid nucleic acid amplification technology at room temperature and constant temperature, its principle is that at room and constant temperature, the recombinase and primer form a protein/single-stranded nucleotide complex Rec/ssDNA, and invade the double-stranded DNA template with the help of auxiliary proteins and single-stranded binding protein SSB; then form a D-loop region at the invasion point and start to scan the DNA duplex, after finding the target region complementary to the primer and disintegration of the complex Rec/ssDNA, the polymerase also binds to the 3′ end of the primer to start the chain extension.
Isothermal Nucleic Acid Product Features
1/ High sensitivity and specificity, short reaction time.
2/ The reagent form is freeze-dried, stable and easy to operate.
3/ The reaction can be operated by metal bath and water bath pot without purchasing expensive PCR apparatus.
