DBCO-PEG8-Maleimide is a PEG linker containing a DBCO moiety and a terminal primary maleimide group. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
DBCO-PEG6-Maleimide is a PEG linker containing a DBCO moiety and a terminal primary maleimide group. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. DBCO is commonly used for copper-free Click Chemistry reactions.

This kit provides a rapid method for the isolation and purification of DNA from formalin-fixed paraffin-embedded (FFPE) tissue samples. Using formalin to fix tissues leads to crosslinking of the nucleic acids and proteins, and the process of embedding the tissue samples can also lead to fragmentation of the nucleic acids over time. Norgen’s FFPE DNA Purification Kit provides conditions that allow for the partial reversing of the formalin modifications, resulting in a high quality and yield of nucleic acids. The purified DNA is of high yield and integrity and is free of inhibitors, ready for use in a number of downstream applications including qPCR, mutation screening, microarray analysis, sequencing, single nucleotide polymorphism (SNP) and short-tandem repeat (STR) genotyping. The protocol can be completed in as little as 1 hour.

The Protein Digestibility Assay Kit (K-PDCAAS) is used for in vitro measurement of the Animal-Safe Accurate Protein Quality Score (ASAP-Quality Score Method) developed under patent by Medallion Labs. This digestibility score, in conjunction with the essential amino acid profile plus protein and moisture content of the sample, is used to calculate the Protein Digestibility Corrected Amino Acid Score (PDCAAS) value.
