Based on the provided search results and current research landscape, here's a structured FAQ addressing key scientific considerations for AT1R-related antibody research (note: "At1g26510" appears to be an Arabidopsis thaliana gene identifier, while the search results focus on AT1R [Angiotensin II Type 1 Receptor] antibodies. This FAQ assumes potential terminology confusion and addresses AT1R antibodies as per available data):
From single-cell RNA sequencing data and knockout models :
Implement multi-center validation protocol:
Reagent validation:
Compare 3 commercial sources via BLI (ForteBio Octet)
Require CV <15% in binding kinetics
Assay standardization:
Use defined CHO-AT1R cells (1×10<sup>5</sup>/well)
Fixed agonist concentration (10<sup>-7</sup> M Ang II)
Cryo-EM with nanodiscs: Resolve extracellular domain conformations at 3.2Å
Microfluidic SPR: Enables parallel characterization of 96 variants/day
Deep mutational scanning: Identify affinity/toxicity hotspots using phage display libraries (>10<sup>6</sup> variants)
Adopt a phased approach:
