Assay Principle
Losatuxizumab ELISA Kit provides plate-based quantitative measurement of Losatuxizumab. Each run carries its own standard series, so results remain comparable across plates, days, and operators in a research workflow.
Background
Losatuxizumab is a biosimilar that targets EGFR. EGFR (Epidermal growth factor receptor, HER1, ErbB1) is encoded by the EGFR gene located on chromosome 7 in humans. EGFR belongs to the HER/ERbB family of proteins that includes three other receptor tyrosine kinases, ERbB2, ERbB3, ERbB4. EGFR is a transmembrane receptor and binding of its cognate ligands such as EGF (Epidermal Growth Factor) and TGF alpha (Transforming Growth Factor alpha) to the extracellular domain leads to EGFR dimerization followed by autophosphorylation of the tyrosine residues in the cytoplasmic domain. Phosphorylation of EGFR at certain residues is also mediated by Src-non-receptor kinase. EGFR activation signals multiple downstream signaling cascades such as the Ras - ERK, pi3-K - Akt, Jak - STAT and PKC pathways that help in growth and proliferation of cells. Phosphorylation of EGFR at Y1086 specifically allows binding of the adaptor protein GRB2, leading to activation of the MAPK pathway. Upon receptor activation and signaling, EGFR is endocytosed and targeted for degradation or recycling. Mutations in the EGFR gene are associated with lung cancer and multiple alternatively spliced transcript variants encode different protein isoforms of EGFR have been found. Increased production or activation of EGFR has been associated with poor prognosis in a variety of tumors. Moreover, EGFR overexpression is observed in tumors of the head and neck, brain, bladder, stomach, breast, lung, endometrium, cervix, vulva, ovary, esophagus, stomach and in squamous cell carcinoma.

Performance Data
The kit provides a quantitative range of 0.31-5 μg/mL, an analytical sensitivity of 0.156 μg/mL, typical spike recovery of 80-120%. Plan sample dilutions so readouts fall within the linear portion of the standard curve, and evaluate matrix effects with dilution-linearity and spike-recovery controls.
Target Notes
The target is also referenced in the literature as ABT-806, PR-1316749. Curated target information is available under UniProt accession P00533. The corresponding compound is registered under CAS 1801544-27-3.
