Binding affinities (Kd) — source-verified (view)

742 distinct verbatim-verified aptamer–target Kd measurements (canonical Gold v1; 555 intrinsic-equilibrium; 300 unique targets; 287 publications; 435 carry a verbatim-verified sequence). ★HOW TO READ: 'kd_reported' is the value EXACTLY as written in the paper (units are MIXED — pM/nM/M — so it is NOT directly comparable). To compare, sort, or train an ML model, use ONLY 'kd_log10_molar' (lower = tighter) and filter measurement_class=intrinsic + target_type=protein. The same target appears in several rows because of different aptamers, assays, conditions (temperature/buffer) or papers — see those columns. For a clean ready-to-use subset use the 'kd_ready_to_use' query. Source: corpus literature-extraction pipeline (E. Dohi).

Data license: CC BY 4.0 · Data source: apt-scout automated curation pipeline (E. Dohi, NCNP) — values harvested from public databases; raw source stored per target

target_name_canonical
Target as named in the source paper.
target_type
protein / cell-line+EV / glycan-conjugate. Filter to 'protein' for molecular targets.
target_uniprot
UniProt accession when a human protein (sparse for now; links to apt-scout target).
aptamer_name
Aptamer identifier as reported.
kd_reported
Kd value AS REPORTED in the paper (value + unit). Units are MIXED — do NOT compare this column directly.
kd_log10_molar
log10(Kd in molar). THE column to sort / compare / learn on (lower = tighter).
measurement_class
intrinsic = equilibrium vs purified target; non_intrinsic = apparent/cellular or avidity (NOT comparable to intrinsic).
binding_constant_type
Kd / apparent-Kd etc. as reported.
assay_method
SPR / filter binding / flow cytometry / ITC / BLI …
assay_temperature_k
Assay temperature (K) — a reason the same pair can have several rows.
source_pmid
PubMed ID of the source paper (links out).
verbatim_quote
The exact sentence the value was taken from.
verification_level
QC status (honest, growing): human_verified / human_corrected = a logged human verdict from the stratified-random sample; multi_agent_verified = passed independent multi-agent (L2) check; extraction_verified = extraction-pipeline verified; automated. Human verification is in progress: as of this release 0 records carry a logged human verdict — the published set is multi-agent-/extraction-verified, and human spot-checking is being added post-publication (version-tracked). No record is labelled human_verified without a logged human review.
sequence_status
Aptamer-sequence provenance: verified_in_text_or_SI = sequence verbatim-verified against the source text/SI (shown); pending_manual_supp / pending_supp_oa / pending_manual_figure = sequence reported only in a (often paywalled) SI or a figure, being curated post-submission; no_single_sequence_pool = a pool/library/primer, no single sequence exists.
pi_provenance_flag
PI manual-review flag: KEEP_seq_in_figure = valid record, sequence is in a 3D-structure figure; FLAG_cited_data = Kd may be a value cited from elsewhere, re-verify. (EXCLUDE rows are hidden from this view.)
seq_source
original (already in source DB) / backfill_text_verified (recovered from paper or SI text).

46 rows where assay_method = "SPR", sequence_status = "verified_in_text_or_SI" and verification_level = "extraction_verified" sorted by kd_log10_molar
