Biotinylated Protein Standards

Overview

Biotinylated Standards

Biotinylated SDS-PAGE standards allow accurate MW determination directly on western blots, and are available in high, low and broad MW ranges.

Detection of biotinylated standards. Steps beyond the procedure for detecting sample proteins are required. Following transfer and addition of antigen-specific primary antibody, avidin-HRP or avidin-AP is added to the conjugated secondary antibody solution and applied to the membrane. Avidin binds to the biotinylated standards while the secondary antibody binds to the primary antibody. The standards and the protein of interest are detected simultaneously using the appropriate color development reagent system.

Discontinued Product
Biotinylated Natural SDS-PAGE Standards have been discontinued. Precision Plus Protein™ WesternC™ Standards are the recommended replacement products. These prestained, Strep-tagged recombinant protein standards enable both fluorescent visualization on gels and colorimetric or chemiluminescent western blot detection with StrepTactin-AP or StrepTactin-HRP Conjugate.

Recombinant protein standards offer reproducible migration patterns and exceptional lot-to-lot molecular weight consistency, and are ideal for western blotting. See the Protein Ladders and Standards page to select the best protein standard for your application.
