Xpress Clones
Xpress Clones are high-quality, pre-validated gene expression clones designed for fast and reliable protein production in a wide range of systems, including bacterial, mammalian, and yeast hosts. These ready-to-use plasmids contain your gene of interest in optimized expression vectors with tags (e.g., His, FLAG, GST) for easy purification and detection. Ideal for functional studies, protein engineering, and structural biology, Xpress Clones eliminate the time-consuming steps of cloning and sequence verification. Each clone is sequence-verified and quality-controlled to ensure high expression efficiency and reproducibility in downstream applications such as Western blotting, ELISA, and cell-based assays. Choose Xpress Clones to accelerate your research and achieve consistent, reproducible protein expression results with minimal effort.

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 .
