Human LZTS1 ELISA Kit (HUFI03550)

Building on the validated Assay Genie protocol, this human LZTS1 immunoassay reports a calibration range of 0.313 to 20 ng/mL with an analytical sensitivity below 0.188 ng/mL, enabling discrimination of low-abundance FEZ1 expression in tumor-adjacent and matched-normal tissue comparisons. Beyond serum and plasma, the manufacturer has independently validated cell lysate and tissue homogenate inputs, expanding the kit's utility for experiments where biopsy material or cultured carcinoma lines such as A549, MCF-7, and KYSE-150 are the preferred analyte. The capture antibody is human-specific, showing no significant cross-reactivity with rat or mouse LZTS1 homologues. Reagents are shipped on cold packs and should be stored refrigerated to preserve activity; the recombinant standard and concentrated detection antibody benefit from aliquoting to limit freeze-thaw cycles and extend shelf life.
