Genova Plus Life Science Spectrophotometer
The new Genova Plus is a UV/visible spectrophotometer dedicated to life science analysis. This spectrophotometer is based on the successful 73 series spectrophotometers therefore it has all of the same features including icon driven software and an improved navigation system for easy and intuitive usability. The Genova Plus has pre-programmed methods for the measurement of nucleic acid concentrations and protein assays. This spectrophotometer also has measurement modes for the purity of nucleic acids and optical density for cell harvesting.
As well as the dedicated life science measurement modes this versatile instrument can also be used as a standard spectrophotometer with measurement modes for photometrics, concentration, multi-wavelength, spectrum scanning, quantitation and kinetics.
The Genova Plus is pre-programmed with methods for the measurement of ssDNA, dsDNA, RNA and oligonucleotide concentrations using wavelengths recorded at 260, 280 and 230nm, with an optional correction at 320nm. This measurement mode has the 260/280 and 260/230 ratios pre-programmed as well as a variable ratio option which enables up to 3 wavelengths to be entered as well as the correction wavelength. A dilution option is also available to calculate the original concentration of diluted samples.
For measuring protein concentrations the Genova Plus is pre-programmed with methods for Bradford, Lowry, Biuret, Bicinchoninic Acid (BCA) and Direct UV assays. This measurement mode allows up to 12 standards, with 3 replicates of each standard, to be measured to create the standard curve.
Bacterial cell cultures are routinely grown until the optical density at 600nm reaches approximately 0.4, which indicates the optimum cell number for harvesting. This measurement mode enables cell growth to be monitored by measuring absorbance. Measurements can be performed at 600nm, 595nm or any other user selected wavelength.
The Genova Plus also enables scanning across the full wavelength range from 198 to 1000nm enabling the purity of nucleic acids to be determined. The multi-wavelength measurement mode allows the sample to be measured at 4 different wavelengths, with ratio calculations and formulae with various factors to calculate concentration.
