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.

Antibody Details
Down Arrow Up Arrow

The F023-420 monoclonal antibody specifically recognizes CD328 which is also known as sialic acid binding Ig like lectin 7 (Siglec-7). CD238 is an I-type lectin of approximately 65 kDa, expressed as a monomer on a major subset of NK cells and a subset of CD8+ cells. It is also expressed at moderate levels on monocytes and weakly on granulocytes. Siglecs (sialic acid/immunoglobulin/lectin) are a family of I-type lectins that bind to sialic acids on the cell surface. They are a family of carbohydrate binding proteins within the immunoglobulin superfamily. Siglecs are integral membrane proteins with extracellular N-terminal, V-set Ig domains, followed by variable numbers of C2-set Ig domains.

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.
