Reacts with ALK-NPM, a chimeric gene product of approximately 80 kDa, which is the result of t(2;5)(p23;q35) chromosomal translocation. The gene at 5q35 encodes for the cell cycle-regulated nucleolar protein, nucleophism (NPM), while the gene at 2p23 encodes a novel receptor tyrosine kinase, anaplastic lymphoma kinase (ALK). The 2;5 translocation results in the expression of NPM-ALK protein, or p80, comprised of the N-terminal portion of NPM (about 40% of the molecule) linked to the entire intracellular portion of ALK. ALK1 antibody recognizes a formalin resistant epitope in both the NPM-ALK chimeric and the 200 kDa normal human ALK proteins. Cytoplasmic and nuclear expression of NPM-ALK is seen in t(2;5)+ cell lines Su-DHL-1 and Karpas 299.

This antibody is routinely tested by flow cytometric analysis. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. The antibody was conjugated with R-PE under optimum conditions, and unconjugated antibody and free PE were removed. Store undiluted at 4°C and protected from prolonged exposure to light. Do not freeze.

Recommended Assay Procedures

We recommend to use the Cytofix/cytoperm solution (Cat. No. 554714) for the cell fixation and permeabilization. Please refer to for technical protocols.

Product Notices

  1. This antibody has been optimized and preassayed with its matched isotype control to be used at the recommended volume of 20 ul/test. Titration of the reagents or substituting with other (non-matched) isotype control is NOT recommended.
  2. Please refer to for technical protocols.
  3. For fluorochrome spectra and suitable instrument settings, please refer to our Multicolor Flow Cytometry web page at
  4. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
  5. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
