    FAQ

    DomandaRisposta
    What is the well depth and maximum volume capacity of a MultiScreen plate?The well depth of a 96 well MultiScreen plate is 1.245 cm. The well depth for a 384 well MultiScreen plate is 1.2 cm. The maximum working volume of a 96 well plate is 300 ul. The maximum working volume for a 384 well plate is 100 ul.
    Why do we recommend addition of 75 µL of medium apically (in the filter well) and 250 µL basolaterally (in the receiver/feeder plate) for the MultiScreen Caco-2 plate?These volumes were determined to be optimal for cell growth when feeding the cell culture every other day. In addition, with 75 µL apical, the medium level is at the same height as the basolateral volume of 250 µL. In this way we ensure that there is no positive pressure exerted on the monolayer of Caco-2 cells.
    Do you recommend any specific handling when feeding the cells on the MultiScreen-Caco-2 plate?We recommend using an autoclavable 8-channel aspiration manifold. Sigma M2656. Drummond #3-000-093 Aspirate/feed apically using the apical notch and down the side of the well (slow speed if programmable).

    If you are feeding manually, feel free to separate the plates to aspirate/feed basolaterally. Due to the fact that the MultiScreen-Caco-2 plate has recessed filter wells, the membrane will not be in direct contact with any surface. The filter plate has 4 feet it stands on.
    Can I add lucifer yellow and drug compounds together in the same well in the MultiScreen Caco-2 plate?We do not recommend using lucifer yellow in the same well as your test compound if you are using radioactive drugs. Lucifer yellow may interfere with scintillation cocktail and give inaccurately high counts in the beta counter.
    Why are the propranolol and testosterone values from Millipore’s laboratory determined on the MultiScreen Caco-2 plate lower than published values?We have speculated that the differences we observe are related more to the cell culture and analytical conditions we employ in our laboratory because the values we observe on the standard 24 well plates are also lower than published. Because we correlate well with the 24 well data generated at the same time in our laboratory, the discrepancy from published is not a concern.
    How do you determine the optimal seeding density on the MultiScreen Caco-2 plate?This requires optimization for each laboratory, due to the variability in Caco-2 cultures. We recommend starting with the same number of cells/cm2 used for a 24 well culture. For example if you are plating 30,000 cells/well in a 24 well plate, you would plate 11,000 cells per well for the MultiScreen Caco-2 (30,000 cells/0.3cm2)(0.11cm2)= 11,000 cells.
    Do you recommend optimal feeding conditions for cells grown on the MultiScreen Caco-2 plate?We recommend feeding every other day (Mon, Wed, Fri.) exchanging apical and basolateral media in a specific order. The preferred order is to aspirate basolaterally first, then apically, and add fresh medium back apically first, then basolaterally.
    What are normal TEERs (Trans epithelial electrical resistance) that are measured on the MultiScreen Caco-2 plate?Generally, TEER values obtained are in the range of 1000-4000 ohms for a 21 day culture and 1000-3000 ohms for a 10 day culture. We consider a failing well below 1000 ohms. If you were using a 24-well plate you can estimate desired TEERs on our plate comparing the surface area. If not, you can estimate a normal range comparing lucifer yellow test results.
    What kind of correlation should we expect between the MultiScreen Caco-2 plate and our current assay plates?Provided careful optimization has been performed on the 96 well plate, the data generated should be comparable to that observed with current 24 well systems.
    Can I grow MDCK cells on the Multiscreen Caco-2 plate?MDCK cells are canine kidney cells that can form differentiated monolayers with tight junctions after 3 days. The permeability values for MDCK correlates well with Caco-2 and human absorption for passively absorbed compounds. In the past we have successfully demonstrated MDCK growth on our Caco-2 plate. We have discovered that cells grown for 3 days are more sensitive to fluctuations in growth conditions. It is crucial that the cell growth conditions are optimized.
