General description

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

Application

Casein Blocking Buffer 10x has been used in:

  • western blotting
  • enzyme linked immunosorbent assay (ELISA)
  • immunohistochemistry

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.

Protocols

10x Blocking Buffer Protocol

Membrane-based blotting applications that employ enzyme conjugates to generate colorimetric or chemiluminescent signal require the use of an added blocking step to decrease the signal generated by non-specific binding.

Northern and Southern Blot Protocols & Introduction

An introduction to both Northern and Southern blotting, popular methods for the transfer of macromolecules to membranous support. This article also offers a Southern blot protocol and a northern blot protocol.
