Not every lab wants to build an ELISA from scratch. Coating, blocking, optimizing antibody pairs, validating standard curves — it works, but it takes weeks. That is why abinScience offers over 400 ready-to-use ELISA kits in pre-coated 96-well format: add your sample, follow the protocol, read the plate. Each kit comes with a matched capture/detection antibody pair, calibrator standards, and optimized buffers — no antibody pairing required.
Our ELISA kit portfolio covers three core application areas: pharmacokinetic (PK) drug monitoring, anti-drug antibody (ADA) detection, and infectious disease antigen screening.
PK Drug Monitoring ELISA Kits
Quantitative sandwich ELISA kits for measuring therapeutic drug concentrations in serum or plasma. Used in preclinical PK studies, bioanalytical method development, and lot release testing. Each kit is designed for a specific biologic drug and validated for sensitivity, linearity, and precision.
266 PK ELISA kits available, covering major therapeutic antibodies, fusion proteins, and peptide drugs. Representative products below:
Anti-Drug Antibody (ADA) ELISA Kits
Bridging or direct ELISA kits for detecting patient immune responses against therapeutic biologics. ADA testing is a regulatory requirement for all biologic drug development programs — these kits enable screening, confirmation, and titer determination of anti-drug antibodies in preclinical and clinical serum samples.
140 ADA ELISA kits available. Representative products:
Infectious Disease Antigen ELISA Kits
Sandwich ELISA kits for detecting viral antigens in research samples. Designed for pathogen surveillance studies, vaccine development, and outbreak response research.
What's Inside Each Kit
| Format |
Pre-coated 96-well microplate (break-apart strips for flexibility) |
| Kit contents |
Coated plate, detection antibody (HRP-conjugated), calibrator standards, sample diluent, wash buffer concentrate, TMB substrate, stop solution |
| Protocol time |
3–4 hours (add sample → incubate → wash → detect → read). No overnight steps required. |
| Detection |
Colorimetric (TMB/HRP). Read absorbance at 450 nm on any standard microplate reader. |
| Sample types |
Serum, plasma, cell culture supernatant (varies by kit — check individual product pages for validated sample types). |
PK vs ADA ELISA: Which Kit Do You Need?
If you are developing or studying a biologic drug, you likely need both types of ELISA kits — but for different questions:
| |
PK ELISA Kit |
ADA ELISA Kit |
| Measures |
Drug concentration in serum/plasma |
Patient antibodies against the drug |
| Answers |
"How much drug is in the sample?" |
"Is the patient developing an immune response against the drug?" |
| Typical format |
Sandwich ELISA (anti-drug capture → drug → anti-drug-HRP detection) |
Bridging ELISA (drug-coated plate → ADA → drug-HRP detection) or direct format |
| Regulatory context |
Required for dose-exposure analysis in all biologic IND filings |
Required for immunogenicity assessment per FDA and EMA guidelines |
