To accurately predict the activity of a transgene it is critical to understand its location and dynamics in the 3-D interphase nucleus. Developed in situ methods to visualize transgenes (including single copy genes) & their transcripts during interphase from different tissues & plant species. These techniques reduce the time necessary for characterization of transgene integration by eliminating the need for time-consuming segregation analysis and extend characterization to the interphase nucleus - [Read In Situ Methods to Localize Transgenes and Transcripts in Interphase Nuclei]

In situ methods to visualize transgenes (including single copy genes) and their transcripts during interphase from different tissues and plant species. These techniques reduce the time necessary for characterization of transgene integration by eliminating the need for time-consuming segregation analysis, and extend characterization to the interphase nucleus, thus increasing the likelihood of accurate prediction of transgene activity. - [Read In Situ Methods to Localize Transgenes and Transcripts in Interphase Nuclei]

Details a placenta specific gene manipulation by transducing blastocysts with lentiviral vectors1. After a removal of zona pellucida which functions as a physical barrier, trophoblast cells lying outermost layer of blastocyst were transduced from outside with high-titer lentiviral vectors. As most placental cells descend from trophoblast cells while fetus originated from inner cell mass, transgene expression can be observed in trophoblast cells from preimplantation stages and in placenta... - [Read Placenta Specific Gene Manipulation by Transducing Zona-Free Blastocyst using Lentiviral Vector]

Method is used chiefly to genotype transgenic and knockout mice. Each 6-10-mm snippet of mouse tail yields 50-100 µg of DNA that can be used in dot or slot blotting to detect a transgene of interest, in Southern hybridization to detect DNA fragments that are <20 kb in size, and as a template in PCRs. - [Read Preparation of Genomic DNA from Mouse Tails and Other Small Samples Protocol]

Simple protocol is used to extract DNA from small numbers of cultured cells and from fragments of soft or bony tissues.  The method is used chiefly to genotype transgenic and knockout mice.  Each 6-10-mm snippet of mouse tail yields 50-100 µg of DNA that can be used in dot or slot blotting to detect a transgene of interest, in Southern hybridization to detect DNA fragments that are <20 kb in size, and as a template in PCRs. - [Read Preparation of Genomic DNA from Mouse Tails and Other Small Samples Protocol]

PCR screens must be designed to detect transgene DNA at the single copy level.Copy standards are prepared by mixing non-transgenic tail DNA with a known amount of transgene DNA to produce transgene copy standards.

This procedure, which uses a root transformation protocol, provides a rapid method for assessing gene expression in Arabidopsis roots. It is useful for testing promoter:reporter gene constructs, for expressing genes, the overexpression of which is lethal in whole plants, and for transforming the roots of plants that are recalcitrant to conventional transformation techniques. The protocol has been used successfully with Ws, No-0, and RLD ecotypes. - [Read Transgene Expression in Regenerated Roots]
