Clone: Lambda DNP Probe Cocktail
Synonyms: Lambda by in situ hybridization
Application: Lambda DNP ISH probes bind to lambda light chain mRNA in formalin fixed, paraffin embedded tissues. In combination with Kappa DNA ISH testing, this assay assists in the demonstration of monoclonal plasma cells and determining immunoglobulin.
Specimen Type: Formalin-fixed, paraffin-embedded tissue blocks (FFPE). If tissue blocks are not available, unstained slides are acceptable (please submit 1-2 slides per antibody to be tested, cuts must be 4 microns thick).
Collection Procedure: Tissue removed during a surgical procedure and placed in 10% NBF soon after removal from the patient. Appropriate tissue for requested staining.
