Description

S-Layer Protein, Haloferax Volacanii is a crystalline surface layer protein extracted from the extremely halophilic archaeon *Haloferax volcanii*. This unique biomaterial is valued for its remarkable self-assembly properties, forming two-dimensional paracrystalline arrays with precise nanopatterns. It serves as a critical component in advanced nanotechnology, biomedical engineering, and biosensor development. Researchers and product developers in the fields of nanobiotechnology, vaccine design, and diagnostic platforms utilize this protein for creating highly ordered, functional surfaces.

Application

• Nanobiotechnology & Biomimetic Materials: As a building block for creating ultra-thin, nanopatterned coatings and functional membranes with precise pore sizes.
• Vaccine & Drug Delivery Platforms: Used as an antigen display system or a biocompatible carrier to enhance immunogenicity and targeted delivery.
• Biosensor & Diagnostic Chips: Immobilization matrix for enzymes, antibodies, or DNA probes to create highly sensitive and stable sensing surfaces.
• Affinity Purification & Chromatography: Functionalized S-layer lattices can be used as selective adsorbents for protein purification.
• Surface Functionalization: Coating of medical devices, implants, or nanoparticles to improve biocompatibility and reduce biofouling.
• Fundamental Research: Study of protein crystallization, membrane biophysics, and archaeal cell biology.

Quality Control

Our S-Layer Protein, Haloferax Volacanii is produced under stringent conditions to ensure batch-to-batch consistency and high biological activity. Each lot undergoes rigorous quality testing, including analysis for purity, structural integrity, and self-assembly capability. Certificates of Analysis (COA) detailing specifications such as purity (by SDS-PAGE and HPLC), protein concentration, and endotoxin levels are available upon request. Production adheres to relevant quality management standards.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized material at 2-8°C. Reconstituted protein solutions should be aliquoted and stored at ≤ -20°C to prevent repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure containers are sealed under anhydrous conditions after each use.
