DBCO-PEG4-Desthiobiotin is a PEG linker containing a desthiobiotin group and a DBCO functional group. Desthiobiotin is used for affinity-based applications such as pull-down assays or for ligating with streptavidin proteins while DBCO is a click chemistry handle that quickly reacts with azide groups on target molecules. Desthiobiotin is a sulfur-free analogue of biotin which binds streptavidin with slightly less strength than biotin, which provides it with a soft-release characteristic that is useful for in pull-down assays by minimizing co-elution with endogenous biotinylated molecules. The inclusion of a PEG linker in this molecule improves its aqueous solubility.

Description
ExcelTaq™ Klen-Taq DNA Polymerase is a specially blended enzyme mix containing KlenTaq-1 DNA polymerase (a 5’-exo-minus, N-terminal deletion of Taq DNA polymerase) and a small amount of a proofreading DNA polymerase. This unique blending helps to improve the fidelity, yield and processivity of the resultant PCR process. The Klen-Taq is also highly robust, showing high tolerance of varying concentrations of Mg2+; it is highly thermostable and has four times the fidelity compared to Taq DNA polymerase. The ExcelTaq™ Klen-Taq DNA Polymerase is ideal for DNA amplifications 0.5-5 kb in length on genomic DNA, and up to 10 kb on less complex templates.
Features
5’→3′ DNA polymerase activity
3’→5′ exonuclease activity (proofreading)
4× fidelity as compared to Taq DNA polymerase
Thermo-stable: up to 98°C during PCR denaturing step
Robust PCR performance, resistance to variance in PCR conditions
Storage
-20°C for 24 months

Aminooxy-PEG1-propargyl is a click chemistry PEG linker containing a propargyl group and an aminooxy group. The aminooxy group is reactive with an aldehyde or ketone group to form a stable oxime linkage. The propargyl group can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.
