Opportunity For A License: Whole Chromosome Painting Probes (WCP
Probes) and Band-Region Specific Painting Probes (Micro-FISH Probes)
Developed by Dr. Paul Meltzer and Dr. Jeffrey Trent, National Center
for Human Genome Research
AGENCY: National Institutes of Health, Public Health Service, DHHS.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The National Institutes of Health seeks non-exclusive
biological materials licensees to commercialize Whole Chromosome
Painting Probes (WCP probes) and Region Specific Painting Probes
(Micro-FISH probes) generated by chromosome microdissection and
amplification of specific regions, and labelled for Fluorescent in situ
Hybridization (FISH). The probes can be hybridized to normal metaphase
chromosomes and used as either diagnostic reagents for identification
of chromosomal abnormalities or as research reagents to further study
various cancers and hereditary diseases.
WCP probes for all human chromosomes are being generated using a
universal primer. The probes are significantly superior to current
probes due to greater sensitivity and selectivity. The subject
invention allows generation of probes for the acrocentric chromosomes
(13,14,15,21 and 22) by elimination of shared ribosomal elements
between these chromosomes.
While numerous whole chromosome painting probes are presently
available, most have technical limitations. Most frequently,
hybridization to portions of the target chromosome is incomplete
because of gaps in the sequence. Additionally, in many cases flow-
sorted chromosomes in rodent backgrounds invariably transfer some
sequences which make these unusable for research analysis with somatic
cell hybrids.
The WCP and Micro-FISH probes address these problems. The probes
can be used to analyze complex chromosome rearrangements in a variety
of malignancies, clearly identifying chromosome rearrangements which
could not be detected by conventional banding analysis. The probes can
also be generated to span translocation breakpoints and identify
interstitial deletions, both of which would confound conventionally
created whole chromosome painting probes.
Beyond improvements in specificity and sensitivity, probes created
by the micro-FISH method eliminate the microchemical steps required by
other methods by using a DNA oligonucleotide primer to directly prime
DNA synthesis at intervals along the microdissected DNA template.
Accordingly, the procedure for probe preparation is dramatically
simplified and accelerated, and since the major losses associated with
the microchemical process are largely eliminated, the probes emit a
stronger and more uniform signal intensity than other commonly
available probes.
NIH is the assignee of the rights for this technology developed by
Drs. Trent and Meltzer of the National Center for Human Genome
Research. The laboratory at the National Center for Human Genome
Research will make dissected chromosomal biological material available
for probe manufacture, through a nonexclusive biological materials
license agreement.
