Moreover, as revealed by in situ hybridization analysis, the GGFs appear to be expressed in the nervous system during embryonic development.

Fluorescent in situ hybridization analysis has shown that activation of var alleles is linked to altered positioning of the genetic material to distinct "transcriptionally permissive" areas.

To ascertain the diagnosis when karyotyping results are unclear or negative, more sophisticated techniques such as subtelomeric fluorescent in-situ hybridization analysis and array comparative genomic hybridization (aCGH) may be used.

In situ hybridization analyses of BMP-6 and BMP-7 indicate that both cell types also express BMP transcripts (P. Lein, unpublished observations).

PHR assisted with comparative genomic hybridization analysis and confirmed all cytogenetic assignments and was the co-supervisor in the project.

These lists of genes are largely validated by the previously described expression pattern in either tissue and by in situ hybridization analysis.

This possibility is consistent with our previous in situ hybridization analyses, which revealed BDNF expression in the peripheral YSL [ 35 ] .

Through fluorescence in situ hybridization analysis, Rouquier [ 15] showed that OR sequences reside at more than 25 locations in the human genome and that the human genome has accumulated a striking number of dysfunctional copies: 72% of these sequences were found to be pseudogenes.

Restriction endonuclease digestion and hybridization analysis of Drosophila genomic DNA revealed that there are several copies of S2 gene (Figure 2).

Fourth, functionally related genes clustered together, demonstrating a coherent pattern in 12 pairs of hybridization analysis (Figures 2, 7).
