HRP substrate, 1-Step™ Ultra TMB-ELISA

Supplier: Thermo Fisher Scientific
Description: The 1-Step™ Ultra TMB-ELISA contains soluble TMB (3,3´,5,5´-tetramentylbenzidine) that is ideal for sensitive ELISA-based applications. TMB is a chromogenic substrate for horseradish peroxidase. Once oxidised by the enzyme, this substrate yields a blue product that absorbs at 370 nm and 652 nm. Adding sulfuric or phosphoric acid to stop the reaction changes the product to yellow that absorbs at 450 nm and provides greater sensitivity than the blue product. The 1-Step Ultra TMB-ELISA is supplied ready to use with no mixing required.

SMART Digest™ Chymotrypsin Kits

Supplier: Thermo Fisher Scientific
Description: SMART Digest™ Chymotrypsin Kits are designed to provide a complimentary digestion option to the SMART Digest™ Trypsin Kits which incorporate trypsin functionality. The Chymotrypsin enzyme functionality allows digestion of proteins at different points of the amino acid chain compared to trypsin. This allows for different/additional structural information to be obtained when trying to characterise a protein. This option can also be used if a protein does not contain the specific point where trypsin cuts the protein chain.

Photoreactive biotinylation reagents, EZ-Link™

Supplier: Thermo Fisher Scientific
Description: Photoactivatable Biotin, Biotin-LC-ASA , Psoralen-PEG3-Biotin and TFPA-PEG3-Biotin each contain a photoactivatable group. When exposed to UV light, they become activated and insert non specifically into nearby molecules. These reagents may be used to label proteins and peptides, but they are also useful in labeling DNA, RNA and other molecules that do not contain any readily reactive functional groups. Psoralen-PEG3-Biotin contains a reactive psoralen group and is
designed to efficiently label nucleic acids. The psoralen group intercalates into the helix of DNA, allowing it to label efficiently and selectively. The psoralen can also stack along with the bases of single-stranded DNA or RNA increasing labeling efficiency and selectivity.
