Thermo Scientific Pierce coomassie brilliant blue dyes are composed of one of the most common forms of coomassie dye, which is a key component of various colorimetric protein gel stains. Coomassie R-250 and G-250 dyes are two chemical forms of a disulphonated triphenylmethane compound that is commonly used as the basis of stains for detection of proteins in gel electrophoresis and bradford-type assay reagents for protein quantitation. The R-250 (red-tinted) form lacks two methyl groups that are present in the G-250 (green-tinted) form, which is also called colloidal coomassie dye.

Gentamicin is widely used for treating tuberculosis and Gram-negative infections and is particularly useful in neonatal intensive care units. Fluorophore-tagged drugs, such as gentamicin-Texas Red (GTTR) conjugates, have been used to identify drug trafficking routes across the BLB and into hair cells, and specifically in the cochlea - the sensory organ responsible for hearing. Identifying the mechanisms involved in the intracochlear trafficking of ototoxic drugs to hair cells is of fundamental as well as clinical importance. Texas Red-gentamicin conjugate (GTTR) provides researchers a valuable tool to study the cellular uptake, kinetics and distribution of gentamicin through fluorescence techniques, such as fluorescence microscopy, fluorescence correlation spectroscopy, single molecule spectroscopy. The TR fluorophore can be conveniently excited from 500-600 nm, with an emission maximum centered around 610 nm. Acute nephrotoxicity and permanent ototoxicity are serious side-effects that increase patient morbidity, or induce permanent auditory and vestibular deficits. Several approaches have been used to study the intracellular mechanisms induced by ototoxic drugs. However, ototoxic drugs must first cross the blood-labyrinth barrier (BLB) before entering sensory hair cells to exert their cytotoxic effect that leads to hearing loss and deafness. The BLB is similar to the blood-brain barrier (BBB), and is composed of tight junction-coupled endothelial and epithelial barrier layers that transport nutrients and ions from one side of the barrier to the other.

The Petri dish filling system, PetriSwiss PS900, is designed for high throughput. All entries are made directly via the screen. No manual is needed. Operator prompting in German or English (other languages can be selected). Automatic device self-diagnosis ensures that the system is ready for operation even before the filling process. The stack height can be freely selected (1 to 20 dishes/stack) and can thus be adapted to ongoing further processing. No need for reloading or counting. The 10-roller pump head ensures uniform and non-pulsatory pumping rates up to 60 ml/min. The AntiDrop function suppresses dripping. These parameters can be defined: Dosing quantity per dish rate; Pause times; AntiDrop function; Media smoothing (Vibramix). The feed unit allows 400 Petri dishes to be loaded. These are filled autonomously and ejected with the preselected stack height on the work bench. Automatic, consecutive alphanumeric dish labelling or barcode application. The printer provides a perfect printed image on a white label. Using thermal transfer printing dispenses with problems relating to dried-on ink and also dispenses with the need for an additional compressor module. Application of the label means that the dish remains unobstructed for colony diagnosis. The incorporated “servicing drawer” greatly facilitates cleaning and maintenance effort. Calculate the dosing quantity of the medium per Petri dish; overall dosing quantity (eg.8,5 L) over the number of dishes (eg. 850 dishes). Vibramix allows you to optimise the filling temperature since it even permits media with high viscosity to be distributed optimally in the dish.
