Product Description:
6xHis-PA28beta is a recombinant protein tagged with a hexahistidine sequence (6xHis) for ease of purification and detection. PA28beta is a subunit of the PA28 (also known as 11S) proteasome activator, which plays a crucial role in enhancing the activity of the 20S proteasome. The PA28beta subunit is involved in antigen processing and presentation, making it important for immunological research.

Key Features:
- High Purity: Produced with high purity levels, suitable for various research applications.
- Tagging: Contains a 6xHis tag for simplified purification using nickel affinity chromatography.
- Functional Activity: Retains its ability to activate the 20S proteasome in vitro.
- Versatility: Can be used in structural studies, functional assays, and protein interaction analyses.

What's Included:
- 6xHis-PA28beta Protein: Provided in a buffer solution that maintains protein stability.
- Certificate of Analysis: Ensures product quality and provides detailed information on purity and concentration.
- User Manual: Instructions for handling, storage, and application protocols.
