tert-Butyl (2-(prop-2-yn-1-yloxy)ethyl)carbamate is crosslinker consisting of a propargyl group and a t-Boc protected amine group. The propargyl group reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry reactions. The t-Boc protected amine can be deprotected under mild acidic conditions. Reagent grade, for research use only.

Cluster of differentiation 2 (CD2) is a useful early T-cell lineage restricted antigen that is present in T-cell differentiation. As a pan-T-cell marker, CD2 staining is used for recognizing practically all normal T-cells, but may be deleted in some T-cell neoplasms. Since CD2 is present in most precursor and mature T-cell leukemias and lymphomas, it is useful in the evaluation of lymphoid malignancies. By using CD2 and CD25 staining, the recognition of systemic mastocytosis and mastocytic leukemia is supported.
