The p53 Kit is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (ELISA). A monoclonal antibody specific for p53 has been coated onto the wells of the microtiter strips provided. Samples, including standards of known p53 concentrations and unknowns are pipetted into these wells. Sample Types: serum, plasma, cell lysate. Range: 3.1-100 U/ml. Sensitivity: 1.5 U/ml. Time: 3h45 ? The Eagle Biosciences Human p53 ELISA is to be used for the in-vitro quantitative determination of p53 in serum, plasma, or cell lysates. The assay will recognize both natural and recombinant p53. The kit recognizes p53 to different extents depending on the source of protein. The Eagle Biosciences Human p53 ELISA Assay kit is for Research Use Only.
