Hydroxy-PEG3-DBCO is a PEG linker containing a DBCO moiety and a terminal primary hydroxyl group. The hydroxyl can react with a variety of functional groups and the hydrophilic PEG spacer arm can provide better solubility to labeled molecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

The NGS Library Quantification Standards with PCR Primers (for Ion Torrent platform) were developed for quantifying the library concentration for ion torrent sequencing platform. Quantification of the library of the fully ligated libraries is important for the quality of the sequencing outcome. Optimal library concentration can increase sequencing yield. Poor library concentration results in bad emPCR, which can lead to low sequencing capacity.
QPCR is the best method for library quantification. Our reagent only amplifies library molecules that will be used for subsequent emPCR, and is optimized for amplification of various samples. Our reagent is compatible with commercial SYBR Green based QPCR reagents. Quantification of library concentration is achieved by comparison with a standard curve generated from DNA Standards.
The kit comprises DNA Standards (six 10-fold dilutions) and a primer mix.

Applications
Storage
-20°C for 36 months
Ultrapure dGTP supplied as sodium salt in purified water (pH 8.5).
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.
