FPS1 antibodies are immunological reagents specifically designed to detect either:
Yeast Fps1: A glycerol channel regulating cellular responses to arsenic stress
Human FPS1: A flavoprotein (iron death inhibition protein 1) involved in ferroptosis regulation
These antibodies enable researchers to investigate protein localization, expression levels, and functional interactions through techniques like Western blotting and immunohistochemistry.
FPS1 antibodies have been instrumental in elucidating:
Human FPS1 antibodies demonstrate:
The CSB-RA029525A0HU monoclonal antibody shows:
Clear separation from control IgG in flow cytometry (FITC signal >10x background)
Consistent performance across fixation/permeabilization protocols
Storage: Maintain at -20°C in 50% glycerol
Working concentrations:
Recent studies highlight FPS1's potential in:
Here’s a structured collection of FAQs tailored for academic researchers working with APS1 autoantibodies (note: corrected from "FPS1" based on search results ), organized by complexity and focused on methodological rigor:
Surface vs. Intracellular Staining:
Blocking: Apply Fc receptor blockers to reduce nonspecific binding in immune cell populations .
Controls: Include isotype-matched antibodies and knockout cell lines to validate signal specificity .
Transcriptomic Correlation: Overlap PhIP-Seq hits with single-cell RNA-seq data from target tissues (e.g., pineal gland) to prioritize antigens expressed in disease-relevant cell types .
Clinical Metadata Linkage: Use machine learning to associate antibody titers with longitudinal patient outcomes (e.g., time-to-organ dysfunction) .
Sequence Homology: Perform BLAST alignment to rule out interspecies cross-reactivity (e.g., human vs. murine isoforms) .
Peptide Library Bias: Address phage-display library underrepresentation of post-translationally modified epitopes by supplementing with custom peptide arrays .
