![Fig. 4. Semiquantitative PCR analysis to evaluate the frequency of vector-carrying cells in the patient's peripheral blood. Patient's mononuclear cells were obtained before the indicated infusion: before gene therapy (lane 1), 2nd infusion (protocol day [D] 21-lane 2), 4th infusion (D 98-lane 3), 5th infusion (D 126-lane 4), 6th infusion (D 175-lane 5), 8th infusion (D 322-lane 6, and 10th infusion (D 462-lane 7), and assayed for the frequency of vector containing cells by semiquantitative PCR. A standard was prepared by diluting cells containing the LASN vector with nontransduced cells. The ratio was determined by comparing the density of the cDNA derived band to that of the genomic DNA derived band.](https://ash.silverchair-cdn.com/ash/content_public/journal/blood/91/1/10.1182_blood.v91.1.30/3/blod4010304.jpeg?Expires=1735547606&Signature=APAwIt~fPOuuCIwcC~eIMTzLjzRu7i-wNUlYinV42csdA-H8KYJU2jTV9w7mmArA-994wlbfWmfTT85ZFs1rlwhN1jRZ4LG2VSud6VTcqmLgV93cT88rC2GsIKewxpmQmGlamtrk5xjJjvqg8Bejr1lc~th73ei4CXbdUtB1RFVR3663f9F3Pai09G7SX56WAEIm4g489EujfKNroCYrSJA-4FiY7Hmm6zYo6TbqQPCoxuVmRRXmLT9sKqhUHpt1678Tl27BfAnjWrLHnvEr4SACqI3jFN3UnkrXX4akitMmKQa6xtmbtxC4x7beJ2Gx2uTI0~tbMZuaP~VZkGMLbA__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
