2019/12/16 · Vial information and sample preparation DI water and a buffer solution were used for the study. The buffer solution was 10mM L-histidine
Typically the wavelength range used in UV detection for HPLC is in the range 200 – 400nm, which covers both UV and the lower part of the visible spectrum. Figure 1 shows the electromagnetic spectrum and the relationship between the wavelength of light and frequency. It should be noted that the shorter the wavelength the higher the energy of
Shim-pack GIS series columns are packed with high purity silica gel and are your ideal generic HPLC columns. Highly uniform particles ensure stable mobile phase delivery and outstanding low pressure. The Shim-pack GIS series not only reduces your cost of solvents, but relieves your system load as well. A uniform silica surface and stable
PD 0325901 is a potent MEK1 and MEK2 inhibitor. PD 0325901 inhibits MEK activity in mouse colon 26 cells (IC 50 = 0.33 nM). PD 0325901 inhibits the growth of melanoma cell lines in vitro and in vivo; induces G 1 -phase cell cycle arrest and apoptosis in a mouse xenograft model. PD 0325901 also inhibits production of proangiogenic cytokines such
Since you see peaks from the crude extract, it suggests that the HPLC system is working. Running standards would confirm this, and also confirm the
Introduction to HPLC High Performance Liquid Chromatography (HPLC) is a process of separating components in a liquid mixture. A liquid sample is injected into a stream of solvent (mobile phase) flowing through a column packed with a separation medium (stationary phase). Sample components separate from one another by a process of differential migration as they
