CASE: ML8500 for hypoxia
Hypoxia is a state in which oxygen is not available in sufficient amounts in the tissue. In vitro study conditions should ideally resemble physiological conditions as closely as possible (e.g. tumor centers are often hypoxic).
ML8500 has an incubation chamber optimized for hypoxia/normoxia experiments. Hypoxia dynamics, optimal gas flow rate, and different oxygen concentrations were optimized to be used for drug studies with ML8500.
CASE: ML8500 protocols for customer preclinical drug validation
Solution: Modulight carried out validation of customer’s protocol in Modulight’s BIOLAB using ML8500 tailored to customer’s final target specifications.
Execution: Customer sent Modulight cells and cell viability dye they are using in their validation protocol.
Result: Modulight carried out protocol in the biolab and prepared a comprehensive testing report for the customer.
CASE: Fluorescence feasibility study
Customer was interested in learning whether their photosensitive drug could be used also for photodynamic diagnosis, so Modulight agreed to perform characterization for the drug.
Work consisted of evaluating the optical properties of the drug by measuring its absorption and emission spectra.
Modulight lasers at different wavelengths were tested together with custom optical imaging filters to compare their feasibility for fluorescence excitation.
The effect of cell internalization was also studied to determine whether that has an impact on fluorescence signal intensity.
Based on these initial results, overall clinical program with this drug will be amended.
CASE: Fluorescence cystoscopy study
Anatomical bladder model, optimized for fluorescence cystoscopy studies.
ML7710 with 405nm laser perfectly suited for cystoscopy together with commercial PDD system, such as from Olympus or Karl Storz.
Tailored imaging optics for customer’s fluorescence drug to be used in bladder visualization and treatment.
ML7710 laser can be used also for PDT/PIT and treatment monitoring with any other drugs, and also to localize tumor using fluorescence diagnostics with either imaging dyes (like ICG, Hexvix) or the inherent fluorescence of the drug compound.
