一般說明
The Whatman Mini-UniPrep G2 is an all in one device that functions both as a filter and a glass autosampler vial for sample preparation prior to UHPLC/HPLC.
- Liquid stored in glass, reducing leaching (specially with organic solvents)
- Works well for aqueous based samples
- Sample only contacts plastic during the actual act of compression
- Improved solvent evaporation rates
- Process samples 3X faster than traditional syringe filter method
- All-in-one device replaces multiple consumables
- Reduce lab waste
- Simplify ordering
- Fewer consumables to store in lab
- Designed to fit any autosampler that accommodate standard 12 x 32 mm vials
特點和優勢
- Features an integrated autosampler vial, plunger with attached filter membrane, and septum/cap
- Borosilicate glass vials eliminate plastic-based leachables that can originate from polypropylene vials
- Designed to hold up to 0.5 mL of unfiltered sample that can then be loaded directly into an autosampler
- Easy to see when a sample has been filtered
- Wide range of membranes with 0.2 and 0.45 µm pore sizes to meet specific requirements
- Also available in amber glass for light-sensitive samples

Vinculin is filamentous (F)-actin-binding protein enriched in integrin-based adhesions to the extracellular matrix (ECM). Whereas studies in 2-dimensional (2D) tissue culture models have suggested that vinculin negatively regulates cell migration by promoting cytoskeleton-ECM coupling to strengthen and stabilize adhesions, its

Blood-brain barrier function is driven by the influence of astrocyte-secreted factors. During neuroinflammatory responses the blood-brain barrier is compromised resulting in central nervous system damage and exacerbated pathology. Here, we identified endothelial netrin 1 induction as a vascular response to

Invasive colorectal cancer is associated with poor prognosis requiring treatment with systemic chemotherapies usually including 5-fluorouracil. A consequence of prolonged treatment is the acquisition of resistance eventually resulting in the recurrence of highly metastatic cancer cells. To address the relationship
