Suspend resin in 100 µl 2x SDS-sample buffer, and heat for 10 min at 95 °C. Centrifuge at 1,800 × g for 3 min at 25 °C and collect supernatant in a fresh tube.The elution is set as a gradient elution, but basically starts at 100% elution buffer right away.

tor. However, these equipments have not been yet applied to gra-dient elution in TLC laboratory practice worldwide. Practition-ers of TLC can solve general elution problem using only one commercially available device so far, i.e., AMD system manu-factured by CAMAG. The procedure of this system is based on the principle worked out The MTT assay is a quantitative cytotoxicity assay that uses a dye called 3- (4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (abbreviated to MTT). MTT is a yellow water soluble chemical that is cleaved by mitochondrial succinate dehydrogenase to form formazan which is violet color. This reaction will only occur in health living cells.Cytotoxicity Testing, MTT Testing Lab Pacific BioLabs

Gel-filtration chromatography is a form of partition chromatography used to separate molecules of different molecular sizes. This technique has also frequently been referred to by various other names, including gel-permeation,gel-exclusion,size-exclusion,and molecular-sieve chromatography. The basic principle of gel filtration is quitePlace the lid on the vertical gel chamber. Insert the red and black wires into the correct matching colored terminals on the power supply.

An elution study is used to collect process data during the regeneration and involves plotting the concentration (specific gravity) of salt during brine draw cycle versus time. The information is then used to troubleshoot and evaluate the ion exchange process. Typical equipment required for an elution study include:Elution was carried out under isocratic condition using HNO 3 (50 mM) at a flow rate of 1.5 mL/min.
