| The most common feature of plasmacytomas, and certain non-Hodgkin’s lymphomas is the restricted expression of a single heavy chain class. Demonstration of clonality in lymphoid infiltrates indicates that the infiltrate is clonal and therefore malignant. Useful in the identification of leukemias, plasmacytomas, and certain non- Hodgkin’s lymphomas. |

| Catalog # | I1890-65H |
| Applications | Suitable for use in Immunohistochemistry. Other applications not tested. |
| Recommended Dilutions | Immunohistochemistry (Formalin/paraffin): 1:250-1:500 for 60 min at RT. Staining of formalin/paraffin tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 min. |
| Optimal dilutions to be determined by the researcher. |
| Positive Control | Tonsil |
| Storage and Stability | May be stored at 4°C for short-term only. For long-term storage, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. |
