Alkali-soluble Casein (5%)

Catalog number: B2012712
Lot number: Batch Dependent
Expiration Date: Batch dependent
Amount: 50 mL
Molecular Weight or Concentration: 0.05
Supplied as: Solution
Applications: molecular tool for various biochemical applications
Storage: 2-8°C
Keywords: blocking buffer, immunodetection blocking buffer
Grade: Biotechnology grade. All products are highly pure. All solutions are made with Type I ultrapure water (resistivity >18 MΩ-cm) and are filtered through 0.22 um.

Alkali-soluble Casein (5%) is a biotechnology-grade reagent formulated for use in immunodetection workflows, protein stabilization studies, and biochemical assay development. Casein, a phosphoprotein derived from milk, is known for its excellent blocking properties and ability to reduce non-specific binding in immunoassays. This 5% solution is solubilized under alkaline conditions and filtered through 0.22 µm membranes using ultrapure water, ensuring high purity and compatibility with sensitive detection systems. Its consistent performance makes it ideal for Western blotting, ELISA, and other applications requiring low background signal.

Researchers working in proteomics, food science, and molecular biology rely on alkali-soluble casein for its ability to stabilize proteins, mask hydrophobic surfaces, and improve assay reproducibility. The 50 mL format provides sufficient volume for multiple experiments, and its storage at 2–8°C ensures long-term usability without degradation. Whether you're optimizing a blocking buffer, studying protein interactions, or developing a diagnostic assay, this reagent offers a reliable and reproducible solution for minimizing assay variability and enhancing signal clarity.

Key benefits:

  • 5% alkali-soluble casein solution for immunodetection and assay blocking

  • Reduces non-specific binding in ELISA, Western blotting, and related assays

  • Filtered through 0.22 µm membranes using ultrapure water

  • Supplied in 50 mL format for scalable experimental use

  • Stored at 2–8°C for long-term stability and performance

Products are for in vitro research use only (RUO).
