Thermo Scientific DyLight microscale protein labeling kits contain NHS ester-activated derivatives of our high-performance DyLight dyes designed specifically for labeling small quantities of antibodies or proteins.

The Qubit Protein Assay Kits are designed to make protein quantification easy while providing accurate quantification. Qubit protein assays require only 10–15 minutes of room temperature incubation, eliminating long incubation periods or exposure to elevated temperatures.

Traditional western blotting is useful for detecting the presence or absence of a specific protein in a lysate or complex mixture. Furthermore, it can provide a qualitative assessment of changes in protein expression levels in response to stimuli or interventions.
