Medchemexpress LLC Pelargonidin (chloride) | 134-04-3 | 99.1% | 306.70 | 5 MG
Pelargonidin chloride is an anthocyanidin that functions as a scavenger of nitric oxide radicals and possesses antioxidant activities. It has been shown to inhibit cell viability and induce cell cycle arrest at the sub-G1 phase. Additionally, it enhances the mRNA and protein expression of HO-1, NQO1, and Nrf2, and improves Aβ-induced memory and learning impairment. It is for research use only.
- Scavenges nitric oxide radicals
- Possesses antioxidant activities
- Inhibits cell viability
- Induces cell cycle arrest at sub-G1 phase
- Increases mRNA and protein expression of HO-1, NQO1, and Nrf2
- Improves Aβ-induced memory and learning impairment
Electron Microscopy Sciences MXS Calibration Standard 301BE for AFM, SEM Unmounted, 300 nm Spacing
EMS offers a series of calibration standards with one and two dimension calibrated patterns. These standards are created utilizing holographic interference of a particular laser frequency. They are typically accurate to <1% across the entire surface of the standard. These reference standards are remarkably durable under typical operating conditions. The surface contamination behavior is also very good. There are no better sub-micron reference standard available in this price range. For AFM, SEM, TOF-SIMS, Auger
Mount: Unmounted
Spacing: 300 nm
Structure: Parallel Ridges
