Human Receptor Tyrosine Kinase (RTK) Phosphorylation Antibody Arrays on Glass Slides are multiplex protein profiling tools designed for the simultaneous detection and semi-quantitative analysis of phosphorylated receptor tyrosine kinases in human biological samples. Based on antibody microarray technology, these arrays use immobilized capture antibodies to detect specific RTKs, while phosphorylation-specific detection antibodies identify phosphorylated forms of these receptors, allowing the assessment of their phosphorylation status. Fluorescence signal intensities provide relative measurements of RTK phosphorylation levels, enabling comparisons between samples.

Key Features

• Multiplex detection: Simultaneous profiling of multiple phosphorylated RTKs within a single sample.

• Phosphorylation-specific analysis: Detection of phosphorylated RTKs using antibodies that recognize specific phosphorylated receptor sites.

• Glass-slide microarray format: Spatially defined antibody spots enable parallel protein detection.

• Semi-quantitative results: Relative fluorescence intensities support comparisons of phosphorylation patterns between experimental conditions.

Usual Research Applications

• Investigating RTK-mediated signaling pathways, including EGFR/ErbB, FGFR and PDGFR signaling.

• Comparing receptor phosphorylation profiles in stimulated versus untreated cells.

• Studying growth factor responses and changes in signal transduction.

• Evaluating the effects of kinase inhibitors and targeted anticancer compounds.

• Exploring altered RTK phosphorylation associated with cancer development, progression and drug resistance.
