PC Biotin-PEG3-alkyne is useful for introducing a biotin moiety to azide-containing biomolecules using Cu(I)-catalyzed Click Chemistry. PEG spacer provides better solubility to the labeled molecules in aqueous media. Captured biomolecules can be efficiently photoreleased using near-UV, low intensity lamp (e.g. 365 nm lamp at 1-5 mW/cm2). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Usages:
For isolation and enumeration of coagulase-positive staphylococci in foodstuffs.
Principle:
Tryptone, beef extract powder and yeast extract powder provides carbon and nitrogen sources, vitamins and growth factors; sodium pyruvate and glycine to stimulate the growth of Staphylococcus aureus; lithium chloride and potassium tellurite inhibit the non-staphylococcal microorganisms; containing lecithinase staphylococcal colonies produce degradation yolk make transparent circle, while the role of the lipase produced an opaque precipitate ring; coagulase-positive staphylococci can restore potassium tellurite and produce black colonies; agar is medium coagulant.

Description
The SMO-HiFi™ DNA Polymerase is a new genetically modified, recombinant DNA polymerase with fidelity 70 times higher than Taq DNA polymerase during amplification, as well as very high elongation rate. Being highly thermostable, SMO-HiFi™ DNA Polymerase can remain viable even after being subjected to boiling for 2 minutes. The SMO-HiFi™ DNA Polymerase is also designed to operate in much lower Mg2+ concentration as compared to other DNA polymerase products.
