Measurement of Gold Nanoparticle Size and Concentration by Spectrophotometry
Although gold nanoparticle production can be controlled to yield specific size ranges, both the concentration and size of nanoparticles must be checked following production.
Smartprep SPE Cartridge System: Automatic Sample Volume Calculation
Analytical methods which extract aqueous samples require that the initial volume of the sample be determined, as it is necessary to calculate the concentration of the analytes in the sample.
UPLC Screening to Preparative HPLC Using CSH Column Technology and Focused Gradients
Reaction screening and purification are essential steps in small molecule pharmaceutical discovery labs.
Modular Spectroscopy Tools for the Simultaneous Measurement of Multiple Sample Characteristics
Modular spectrometers and accessories can be combined for measurement of various spectral characteristics. In this application note we describe a spectrometer and multifunction accessory appropriate for measurement of absorbance, fluorescence, scattering or any combination of these phenomena.
Determination of Mercury in Waters by U.S. EPA Method 245.1 Cold Vapor Atomic Absorption Spectroscopy
Mercury is a toxic element found throughout the environment. Its mobile nature allows it to diffuse through the air, soils and ultimately into water systems. Fish have the ability to bio-accumulate mercury (in its methylated form) at much higher concentrations than the waters they inhabit. People and wildlife that consume fish high in mercury are at risk.
Using the NanoDrop 3300 Fluorospectrometer for Cancer Research Applications
Epigenetic modifications are defined as heritable information other than nucleotide sequences (1) that have the ability to control how and when transcription takes place. DNA methylation and secondary DNA structures such as DNA Gquadruplexes are among the epigenetic modifications currently under study because of their common associations with cancer (1,2).
Extraction and Concentration Solutions
The Extraction System B-811 and the Syncore Analyst parallel concentrator as well as the Pressurized Solvent Extractor were evaluated for the pretreatment of samples containing polycyclic aromatic hydrocarbons (PAHs).
Automated Detection of Drug-Induced Lysosomal Cytotoxicity - Automation of the Lyso-ID Red Assay Using the EL406 Combination Washer Dispenser
Almost all drug compounds will elicit deleterious effects on cells at some concentration. Lysosome perturbation as a result of ion trapping of amine containing compounds has been demonstrated to cause the formation of autophagosomes and autophagic cytopathology. Here we describe the use of the EL406 Combination Washer Dispenser to automatically aspirate media, wash cells and dispense reagents for the Lyso-ID Red Detection kit, part of the CELLestial Live Cell Analysis platform from Enzo Life Sciences.
Determination of Heavy Metals in Wine Using Simultaneous ICP-OES with Mini Torch
Wine is one of the oldest cultural products in human history. Vines have been cultivated for over 8000 years. The oldest known archaeological evidence of winemaking is an 8000-year old wineand fruit press found near Damascus. Awareness of the medicinal effects of wine also date back to this time.
