Product Uses
Historically, T Cell Receptor Gamma Chain Gene Rearrangement Assays have been used to:
  1. Identify clonality highly suggestive of T-cell and some immature B-cell malignancies
  2. Determine lineage involvement in mature lymphoproliferative disorders
  3. Monitor and evaluate disease recurrence
Overview
InVivoScribe Technologies' assay are standardized PCR-based tests. Each test comes with a Standard Operating Procedure (SOP), an interpretation guide, master mixes, and controls. Master mixes are composed of a buffered magnesium solution, deoxynucleotides, and multiple primers that target the gene segments of interest. Multiple primers are used to ensure a more comprehensive testing approach necessary to reliably identify clonal rearrangements. These tests are complete with the exception of Taq DNA Polymerase, which is not provided. A single thermocycler program and similar detection methods are used within each series of test to improve consistency, reduce human error, and facilitate cross training.

Description
NOTICE: Invivoscribe’s T Cell Receptor Gamma Gene Rearrangement Assay 2.0 represents an improved approach to PCR-based clonality testing of T-cell lymphoproliferative disorders. This assay was optimized using a single amplification reaction with a single fluorescent dye for detection. Amplified products generated targeting the TCR gamma gene locus all fall within a single size range to facilitate interpretation.

BACKGROUND: The human TCR gamma gene locus on chromosome 7 (7q14) includes 14 V genes (6 of these V genes are functional; 3 open reading frames, and 5 pseudogenes) belonging to 4 subgroups (Group I, II, III, and IV), 5 J segments, and 2 C genes spread over 200 kilobases. The diversity of this locus has complicated PCR-based testing. This multiplex PCR assay represents an improvement over existing assays as it can detect the vast majority of TCR gamma gene rearrangements with a single multiplex master mix. Importantly, this assay includes primers for all known groups of TCR gamma variable region genes and joining region genes involved in rearrangements in T-cell lymphomas. In addition, all labeled primers are conjugated with the 6FAM fluorophore. The assay provides rapid TCRG clonality assessment in 4-6 hours.

Our single multiplex master mix targets all conserved regions within the variable (V) and the joining (J) region genes that are described in lymphoid malignancies. Click to read more
