Preparation And Storage

The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. Store undiluted at 4°C.

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. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
  2. Please refer to for technical protocols.
  3. 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.

Reacts with NPM-ALK, 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 nuclolar protein nucleophosmin (NPM), and 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 and fluorescence microscopy. Other applications were tested at BD Biosciences Pharmingen during antibody development only or reported in the literature.

Format Details
Down Arrow Up Arrow
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
