The IGH Somatic Hypermutation Assay v2.0 is used to identify clonal rearrangements of the immunoglobulin heavy (IGH) chain gene and determine the somatic mutation status of the variable (V) gene sequence in patients with chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL).
Specifically, the IGH Somatic Hypermutation Assay v2.0 can be used to:
- Identify clonal rearrangements of the IGH chain gene
- Assess the extent of somatic hypermutation in the variable region of the immunoglobulin heavy chain gene
- Evaluate new research and methods in malignancy studies
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.
Standard Protocol.
50ul Total PCR Reaction Volume:
- Using gloved hands, remove the master mixes from the freezer. Allow the tubes to thaw; then gently vortex to mix.
- In a containment hood or dead air box remove an appropriate aliquot to clean, sterile microfuge tube (one tube for each of the master mixes). Aliquot volumes should be 45ul for each sample + 135ul for the positive, negative and no template controls. We recommend adding an additional 20ul to correct for pipetting errors.
- Add the appropriate amount of either AmpliTaq Gold or AmpliTaq DNA polymerase (0.25ul of either AmpliTaq Gold or AmpliTaq @ 5U/ul per 50ul total PCR reaction volume) to each of the master mixes and gently mix by inverting several times or gently vortexing.
- Aliquot 45ul of master mix to individual wells of a PCR plate.
- Add 5ul of DNA from the unknown and control samples to individual tubes or wells containing the respective master mix reactions, and pipette up and down several times to mix. Amplify target DNA using the universal thermocycler program.
