Histology laboratory reagents:
Primary antibodies to CD2 (clone 11F11) and CD7 (clone LP15).
Labelled NovocastraTM and BondTM both manufactured by Leica Biosystems.Antibody specific for CD2 (11F11) is intended for the qualitative identification by light microscopy of CD2 molecules in paraffin-embedded tissue sections. CD2 (11F11) is recommended for use as part of an antibody panel for the characterization of T cell disorders.
Antibody specific for CD7 (LP15) is intended for the qualitative identification by light microscopy of CD7 molecules in paraffin-embedded tissue sections. CD7 (LP15) is recommended for use as part of an antibody panel for the classification of tumours of T-cell origin.

Primary antibody to CD2 (clone 11F11) has been labelled as CD7 (clone LP15).
Conversely, primary antibody to CD7 (clone LP15) has been labelled as CD2 (clone 11F11).
Antibody expression may vary between T-cell proliferations and T-cell lymphoma. There is a risk of misclassification of lymphoma tumours and subsequent delay to diagnosis or delayed or inappropriate treatment.Leica Biosystems issued a Field Safety Notice
(128Kb) warning that various lot numbers of the products listed, primary antibodies to CD2 (clone 11F11) and CD7 (clone LP15), have been mislabelled during the manufacturing process. The product labelled as CD2 is actually CD7 antibody and the product labelled as CD7 contains CD2 antibody.
Where staining with CD2 antibody occurs instead of the expected CD7 antibody this may lead to the failure to identify a reduction in CD7 expression and a potential delay in the diagnosis of lymphoma.
The investigation into the root cause of this issue is ongoing.
