Device fluorescence in situ hybridization, chromosome 17p deletion (tp53)
Definition A chromosome 17p deletion (TP53) fluorescence in situ hybridization (FISH) kit is a test to detect deletion of the TP53 gene in peripheral blood specimens from patients with B-cell chronic lymphocytic leukemia (CLL).
Physical State Probe Kit consists of slide preparation materials, fluorescent FISH probes, buffers and nuclear counterstain, followed by manual signal enumeration using a fluorescence-enabled microscope.
Technical Method The assay uses fluorescence in situ hybridization to identify a deletion in chromosome 17 at the TP53 gene locus in peripheral blood from CLL Patients.
