人食道鳞状细胞癌 disease models

KYSE-410 (Esophageal squamous cell carcinoma). Standardized family protocols with foolproof steps, flowcharts, and methodology PubMed refs—optimize per datasheet and pilots. Research use only (RUO).

Adapted from PubMed literature for research use only (RUO); adjust per lab SOP and pilots.

Use case

Use KYSE-410 in 2D culture to test how compounds or genetic perturbations affect proliferation/survival—baseline solid-tumor readout.

In one line

Stable culture → seed overnight → dose matrix → timed viability/apoptosis → compare vs vehicle.

Protocol overview

01
Expand; log passage
02
Seed plates to assay density
03
Attach / stabilize overnight
04
Add dose matrix + vehicle
05
Incubate to endpoint
06
Viability / apoptosis assay
07
Compute IC₅₀ or % inhibition

01[Prep] Confirm complete medium per datasheet; mycoplasma-negative before key assays.
02[Seed] Count and plate so cultures are ~40–70% confluent at dosing; overnight for adherent lines.
03[Dose] Vehicle + ≥5-point log dose grid; optional cytotoxic positive control. Keep DMSO ≤0.1–0.5% if possible.
04[Incubate] Typically 24–72 h; minimize disturbance.
05[Viability] MTT / CCK-8 / CellTiter-Glo per kit; ≥3 wells/group.
06[Optional apoptosis] Annexin V / caspase or DNA fragmentation.
07[Optional colony] Low-density plating, 1–3 weeks, crystal violet colony counts.
08[Calculate] % inhibition vs vehicle; fit IC₅₀; ≥2–3 independent repeats.
09[QC] Log passage and serum lot; exclude contaminated/detached wells.
