-Plate out. Use 250 μl of the transformed cells.

*If you expect the transformation to be very efficient (for instance using undigested plasmid DNA) first make dilution (1:10 or 1:100 ) and plate 250 μl of this

-
*If you expect the trasformation to be inefficient, concentrate cells by spinning the 500 μl and resuspending the pellet in 250 μl, which you will use for plating.
