BSA Azide

BSA Azide is commonly used positive control for click chemistry-based enrichment of azide-tagged proteins. Bovine Serum Albumin (BSA) is chemically modified on a single cysteine residue with Azide-PEG3-Maleimide (MW 369.37).

Provided as lyophilized solid. To prepare a working 1 mg/ml solution, resuspend lyophilized BSA-conjugate in 500 µl of 0.5 x PBS pH 7.4. DO NOT ADD sodium azide.
