NH-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are joined together at a secondary amine. Terminal alkynes are reactive towards azides in copper (I) click chemistry to form stable triazoles with the target compound. The secondary amine joining the two arms can be used as a nucleophile such as in alkylation via reductive amination or in forming amides with carboxylic acids or activated NHS esters. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.

Description
The ExcelTaq™ Blood Direct DNA Polymerase is designed for amplifying targeted DNA directly from whole blood, eliminating the need for a lengthy DNA isolation process. ExcelTaq™ Blood Direct DNA Polymerase is highly tolerant in the presence of PCR interfering/ inhibiting substances in blood, such as IgG, hemoglobin, and lactoferrin. ExcelTaq™ Blood Direct DNA Polymerase is compatible with most anticoagulants, such as citrate, EDTA, and heparin (Fig. 1). The ExcelTaq™ Blood Direct DNA Polymerase includes a pair of Positive Control Primers (CCR5) that are compatible with primate blood samples.

Tau proteins are abundant in neurons of the central nervous system, and function in microtubule stability and organization. Defects in Tau functioning and aggregation of these proteins have been clinically linked to a number of neurodegenerative disorders including Alzheimer’s disease, Parkinson’s disease, Pick’s disease (PiD), progressive supranuclear palsy (PSP), cortical basal degeneration (CBD), and frontotemporal dementia with parkinsonism linked to chromosome 17 (FTDP-17).
N-t-Boc-Aminooxy-PEG4-N-(PEG2-Propargyl) is a click chemistry crosslinker. The propargyl group is reactive with azide-containing compounds or biomolecules through copper catalyzed Click Chemistry to yield a stable triazole linkage. t-Boc-aminooxy can be deprotected under mild acidic conditions. The hydrophilic PEG linker improves solubility in aqueous media.
