    • An ultrathin mesh optical panel and a method of use and making are disclosed. One embodiment of the optical panel includes a plurality of optical waveguides, wherein each optical waveguide is formed of a mesh material surrounding an optically clear core. The optical panel further includes a light generator. Each optical waveguide internally reflects the light incoming at the inlet of the waveguide to the outlet of the waveguide. The optical panel may optionally include a light redirecting coupling layer and/or a diffuser. An alternate embodiment of the ultrathin optical panel includes a plurality of optical waveguides, wherein the mesh material serves as the light transmissive material. A method of making and using is applicable to both major embodiments. A modification of either embodiment is disclosed wherein the optical waveguide is aligned to be non-perpendicular to the panel face.

    • Titration is an important and critical step in dosing recombinant virus for gene therapy. A relatively fast, convenient and sensitive method that allows for precise quantification of recombinant retrovirus is presented. The method is based on PCR amplification of a foreign gene by the PRINS (primer in situ DNA synthesis) technique. The PRINS technique is based on the sequence-specific annealing of unlabeled oligonucleotide DNA in situ. This oligonucleotide operates as a primer for in situ chain elongation catalyzed by the Taq I polymerase. Using -labeled nucleotides as a substrate for chain elongation, the neo-synthetic DNA is labeled by an FITC-conjugated anti- antibody. To avoid the possibility of false positives, the puromycin resistance gene, which is associated with the transgene in the same viral vector and is not normally present in mammalian cells was amplified. The retroviral titer was evaluated by counting FITC-positive cells after PRINS labeling, while knowing the number of cells that were transduced with different amounts of viral supernatant. A comparable viral concentration of 1 X 10 7 infectious units/mL was found among the retroviruses.
    • 滴定是给予重组病毒进行基因治疗的重要和关键步骤。 提出了一种相对快速,方便和灵敏的方法,可以对重组逆转录病毒进行精确定量。 该方法基于PRINS(引物原位DNA合成)技术对外源基因的PCR扩增。 PRINS技术是基于原位未标记的寡核苷酸DNA的序列特异性退火。 该寡核苷酸作为由Taq I聚合酶催化的原位链延长引物。 使用标记的核苷酸作为链延长的底物,新合成的DNA用FITC缀合的抗体标记。 为了避免假阳性的可能性,扩增了与同一病毒载体中的转基因相关并且通常不存在于哺乳动物细胞中的嘌呤霉素抗性基因。 通过在PRINS标记后计数FITC阳性细胞来评估逆转录病毒滴度,同时知道用不同量的病毒上清转导的细胞数。 在逆转录病毒中发现1×10 7感染单位/ mL的相当的病毒浓度。
