The strategy for creating the Cep97Δ deletion is as follows and is illustrated in the accompanying figure. Two Homology arms were cloned into the pGX-attP vector using 1. Not1 and Nde1 for the NT-Frament and 2. Nsi and StuI for the CT-Fragment We used the following primers Cep97_KO_pGX_FR1-F(Not1) Ggggacaagcggccgcggcgaaagtcttgtttatttttg Cep97_KO_pGX_FR1-R(Nde1) Ggggacaacatatgttttctgattggcaggccgaaattc Cep97_KO_pGX_FR2-F (Nsi) Ggggacaaatgcatacaaatcccagttaataaatg Cep97_KO_pGX_FR2-R (StuI) Ggggacaaaggccttcgcacattttcatgtgggttc This resulted in a replacement of the Cep97 CDS with the white gene. 24bp before the start ATG and 54bp before the stop codon.
