General description

Casein ist ein Phosphoprotein in Milch. Es wird in vier Subtypen unterteilt, d. h. αS1-, αS2-, β- und κ-Casein.[1]
Der 10x Blockierungspuffer von Sigma ist ein caseinbasiertes Blockierungsmittel, das routinemäßig verwendet wird, um die unspezifische Bindung von Nachweisreagenzien[1] an die Northern- und Southern Blot-Membran zu reduzieren.

Application

Anwendungsgebiete von Casein Blockierungspuffer 10x:

  • Western Blotting[2][3][4]
  • Enzyme-linked Immunosorbent Assay (ELISA)
  • Immunhistochemie

Features and Benefits

  • Bessere Blockierungsleistung als Milchpulver oder BSA
  • Einfach zu verwendendes Konzentrat
  • Mit neutralen und positiv geladenen Membranen kompatibel
  • Mit Chemilumineszenz- und Kolorimetrie-Detektionsassays kompatibel

Preparation Note

10x Blocking-Puffer vor Gebrauch mit Wasser von molekularbiologischer Qualität verdünnen.

Fragen

1-8 von 8 Fragen  
  1. Is Casein Blocking Buffer (B6429) compatible with SSC-based pre-hybridization or hybridization buffers for Northern blotting (e.g. 6× SSC, 0.5% SDS) with directly fluorescently labeled probes, or is it intended only for post-hybridization blocking steps?

    1 Antwort
    1. The 10X Casein Blocking Buffer is recommended for both colorimetric and chemiluminescent detection. It is used as a blocking solution for detection, which occurs after hybridization and is suitable for Northern and Southern applications.

      Please also review our Technical Document, Northern & Southern Blot Protocols, available at the link below:

  2. Hi, how much time can be the casein blocking buffer 10X stored from its opening?

    1 Antwort
    1. This product does not have an expiration date once opened. The datasheet indicates the following regarding storage and stability:

      Storage/Stability: Store the 10X Casein Blocking Buffer at room temperature. It is also stable when stored at 2–8°C. Casein may precipitate over time, which is normal and should not impact the performance of the 10X Blocking Buffer. If precipitation is observed, resuspension of the solids can be achieved by inverting the bottle several times or by vortexing for a few seconds.
