General description

Casein is a phosphoprotein found in milk. It is classified into four subtypes, including αS1-, αS2-, β-, and κ-caseins.[1]
Sigma’s 10x Blocking Buffer is a casein-based blocking agent routinely used to reduce non-specific binding of detection reagents[1] to the Northern and Southern Blot membranes.

Application

Casein Blocking Buffer 10x has been used in:

  • western blotting[2][3][4]
  • enzyme linked immunosorbent assay (ELISA)[5]
  • immunohistochemistry[6]

Features and Benefits

  • Better blocking performance than dried milk or BSA
  • Easy-to-use concentrate
  • Compatible with neutral and positively-charged membranes
  • Compatible with chemiluminescent and colorimetric detection assays

Preparation Note

Dilute 10x Blocking Buffer with molecular biology grade water before use.

Optional
