CaLC4499: To C terminally TAP tag Swi6 in a mutant heterozygous for SWI6, the TAP-ARG4 cassette was PCR amplified from pLC57362 using primers oLC3428 in combination with oLC3429 and transformed into SWI6/swi6::FRT. Transformants prototrophic for arginine were PCR tested with oLC3430 in combination with oLC1593 and oLC3430 in combination with oLC3431.
