I worked at that time in that lab and I completed the very first isogenic SV129 K.O. constructs for the planned partial K.O of the CD44 gene. Part of my work contributed to the paper above and was acknowledged within the article: "The sizes of the PCR products derived from the phage clones allows an estimate of the intron sizes. These results have been indepentently confirmed by mapping the restriction sites for more than twenty restriction enzymes on (lambda) phage inserts(R.Eibl, unpublished results)."
