APC/ PE Conjugation

Allophycocyanin (APC) and Phycoerthyrin (PE) are two types of phycobiliproteins that are strongly fluorescent. Due to their high quantum efficiencies, large Stoke shifts, high water solubility, and stability under a wide range of pH and salt concentrations, APC and PE are commonly used fluorescent labels for a wide range of biological applications. LakePharma offers services to custom conjugate APC and PE to proteins at a specified Fluorophore-to-Protein ratio.

Please contact LakePharma at inquiries@lakepharma.com for custom quotes and details.
