CD79a
Use
CD79a is a pan B-cell marker that first appears during the pre-B-cell stage, early in maturation, and persists until the plasma cell stage where it's found intracellularly. It is useful as a marker in antibody panels to differentiate classic Hodgkin lymphoma from nodular lymphocyte predominant Hodgkin lymphoma and aggressive B-cell lymphomas that may show Hodgkin-like features.
Special Instructions
Fresh Tissues: Specimens may be fixed in formalin for 24-72 hours by collection sites, then transferred to 70% ethanol and stored at 2-8°C for longer term storage if needed. Samples must be tested 3 months after placing in ethanol. Unstained slides: Positively charged glass slides required to prevent background staining and prevent tissue loss. Slides should be left unbaked.
Limitations
Stated turn-around-times (TATs) are for clinical use only and subject to change based on biopharma protocol requirements. Final TATs will be specified in the biopharma study contract. Specimens must be fixed in 10% NBF or B plus. All other fixatives will be rejected.
