Viral Proteins
Viral Proteins are essential biomolecules produced by viruses to facilitate infection, replication, and interaction with host cells. These proteins include structural components such as capsid and envelope proteins, as well as non-structural proteins that regulate viral genome replication and immune evasion. Studying viral proteins is crucial for understanding viral pathogenesis, vaccine development, and antiviral drug design. Our collection of high-quality viral proteins offers researchers reliable tools for virology, immunology, and molecular biology studies, enabling breakthroughs in infectious disease research and therapeutic innovation.

Grid Membrane-Specifications

Grid Membrane-Features
- Quality control begins with the QA of raw materials and maintained during and post-membrane casting process through regular sample testing intervals that includes microbial testing and particle counts.
- Gridded lines do not inhibit colony growth.
- All membrane filters comply with ISO 7704.
- MCE membranes is a mixture of cellulose nitrate and cellulose acetate which allows effective retention with high-flow rates and optimal colony growth.
- Each shipment includes COA ( Certificate of Analysis) or Quality Certificate .
