Mix cells gently and incubate for an additional 15 minutes at room temperature in the dark. Wash twice with wash medium (PBS + 1 % BSA, 0.1 % NaN 3, 1 % FBS). The pellet becomes less cohesive on the second wash, so use caution to avoid losing cells.

Web14. aug 2024 · Perkin’s condensation is an example of chemical properties of aromatic aldehydes only. In this reaction aromatic aldehydes condense with an acid anhydride to yield α - β - unsaturated acids. Intermediate involved in Perkin reaction is (a) carbocation (b) carbanion (c) free radical (d) carbene Webdetermined using the Folin–Ciocalteu reagent according to the method described by Kumar et al. (2008). Gallic acid was used as a standard. In this method, the reaction mixture was composed of plant extract (100ll/mL), 500lL of the Folin–Ciocalteu reagent, and 1.5mL of sodium carbonate (20%). The mixture was shaken and made up to 10mL using boy characters with curly hair
