Protein Quantitation Assay

Our new High Sensitivity Protein Quantitation Assay Kit utilizes a fluorogenic detection dye to measure primary aliphatic amines (peptides or proteins) in various samples with much greater sensitivity than the conventional colorimetric protein determination methods.

Protein Phosphorylation Reagents

Phosphoproteins represent an important part of cell signaling research. Standard methods used in protein analysis are often not sufficient for use with phosphoproteins. We have developed reagents that are specifically designed to improve your phosphoprotein research:

• PhosphoBLOCKER Blocking Reagent was designed to provide superior blocking compred to dry milk or serum; it enhances low level phosphoprotein signals without increasing background, and it preserves phosphoproteins during Western blotting.
• Our Phosphoprotein Purification Kit provides enrichment of phosphoproteins by affinity purification using a single-step matrix.
• Our Phospho Antibody Stripping Solution removes phosphoantibodies from blots without affecting the immobilized proteins, allowing you to re-probe with the same or a different antibody.   

His-Tag Protein ELISA Kit

Our His-Tag Protein ELISA Kit allows you to detect and quantify His-tagged protein samples simply and reliably by comparing your unknown samples to a known recombinant standard.

Sensitivity range of the kit is 4 µg/mL to 1 ng/mL, or 950 nM to 50 pM of 6xHis-tag residues.
