Assay Kits

Choose from 400+ ready-to-use assay kits — including sandwich ELISA, competitive ELISA, anti-drug antibody (ADA), and pharmacokinetic (PK) assay kits — designed for quantitative biomarker detection, immunogenicity assessment, and drug monitoring. Each kit ships with pre-coated microplates, optimized reagents, and validated standard curves. Lot-specific CoA with sensitivity, recovery, and precision data included. All products are designated Research Use Only (RUO) — not intended for diagnostic or therapeutic procedures. RUO

Why Researchers Choose abinScience

High Sensitivity & Specificity Optimized antibody pairs deliver pg/mL-level detection. Each kit is validated for minimal cross-reactivity across related analytes.

Pre-Coated & Ready to Use Microplates arrive pre-coated and blocked — just add sample and reagents. Total assay time typically 3–5 hours with no overnight incubation required.

ADA & PK Assay Kits Purpose-built kits for immunogenicity and pharmacokinetic studies — supporting anti-drug antibody screening and drug concentration monitoring in preclinical and translational workflows.

Multi-Species & Multi-Sample Validated across serum, plasma, cell culture supernatant, and other biological matrices. Species coverage includes human, mouse, rat, and more.

Complete Kit Components Every kit includes: pre-coated plate, standard, detection antibody, HRP conjugate, TMB substrate, wash buffer, and detailed protocol — no additional reagents needed.

How to Select the Right Kit

1 Assay Type: Choose sandwich ELISA for cytokines, growth factors, and soluble receptors. Use ADA kits for immunogenicity screening and PK kits for therapeutic drug monitoring.

2 Sample Type & Species: Confirm that the kit is validated for your sample matrix (serum, plasma, supernatant, urine, etc.) and species of interest.

3 Sensitivity & Range: Match the kit's detection range to your expected analyte concentration. Check the standard curve range and minimum detectable dose (MDD) on the datasheet.

4 Throughput: Standard kits include a 96-well plate (96T). For high-throughput screening, contact us for bulk packaging or custom plate configurations.

FAQs

How should I store the kit?

Store unopened kits at 2–8°C. Do not freeze pre-coated plates. Once opened, use remaining strips within 1 month when stored in the sealed pouch with desiccant at 2–8°C.

Can I use serum and plasma interchangeably?

In most cases, yes — but concentrations may differ between matrices. We recommend running a pilot comparison if switching sample types. Check the product datasheet for validated sample types.

What is the difference between ADA and PK assay kits?

ADA (Anti-Drug Antibody) kits detect immune responses against therapeutic antibodies — used for immunogenicity assessment. PK (Pharmacokinetic) kits measure drug concentration in biological samples — used for dose-exposure analysis and drug monitoring.

What plate reader settings are recommended?

Read at 450 nm with a reference wavelength of 630 nm (for TMB substrate). Read within 15 minutes of adding stop solution. Use a 4-parameter logistic (4PL) curve fit for standard curve calculation.

Are these kits RUO or IVD-certified?

All kits are Research Use Only (RUO) unless explicitly labeled otherwise. For IVD-grade or custom assay development, contact our team.
