Leukocytes

This 1 ml liquid antigen reagent from Antibodies.com is prepared from pooled peripheral blood leukocytes that have been disrupted by sonication to release both membrane-bound and intracellular protein targets. The resulting lysate is supplied as a ready-to-use suspension, allowing direct incorporation into immunoassay workflows without additional lysis or clarification steps in the laboratory.

Researchers commonly apply this preparation to antibody development projects, including screening hybridoma supernatants, characterizing anti-leukocyte reagent candidates, and generating positive-control antigen material for cell-marker immunoassays. Because the starting material represents a heterogeneous leukocyte population, the lysate presents a spectrum of native epitopes relevant to neutrophil, lymphocyte, and monocyte lineages, supporting both polyclonal reagent evaluation and exploratory specificity work.

Handling recommendations include protecting the vial from light, refrigerating the product upon receipt, and aliquoting into smaller portions to limit repeated freeze-thaw events that can degrade native antigen. The single 1 ml vial of liquid sonicated leukocyte preparation is intended for research use only and supports small-batch immunoassay calibration as well as larger validation studies that require a consistent whole-cell antigen reference.
