ELISA Manufacture Pipeline

Detection Principle & Protocol
An ELISA protocol involves coating a microplate with a specific capture antibody, adding the sample containing the target analyte, and incubating to allow binding. After washing to remove unbound substances, a detection antibody (linked to an enzyme) is added, followed by a substrate solution that produces a measurable color change. The optical density (OD) is read using a spectrophotometer, with absorbance values correlating to analyte concentration.

What are Therapeutic Antibodies & ADAs?
- Therapeutic mAbs | Designed to bind specific targets and modulate the immune responses or block disease-related pathways.
- Biosimilars | Highly similar versions of approved therapeutic mAbs, while offering a more cost-effective alternative.
- Anti-Drug Antibodies (ADAs) | Immune-generated antibodies that can bind or neutralize therapeutic mAbs, reducing effectiveness.

Why is drug monitoring important ?

- Optimized Dosing | Ensures therapeutic drug concentrations remain within the optimal range for maximum efficacy.
- Reduced Immunogenicity | Prevents overdosing-related side effects and identifies ADA formation that may reduce drug effectiveness.
- Personalized Treatment | Enables dose adjustments based on individual patient responses, improving long-term outcomes
Applications & Data
Therapeutic mAb & Biosimilar ELISA
- Quality Control | ELISA can be used for QC during the development and manufacturing of antibodies
- Biosimilarity assessment | Test similarity between biosimilar and reference product
- PK studies | Assess how mAbs move through the body and help to determine optimal dosing.
- Clinical Development | Monitor the presence of therapeutic & biosimilar mAb in patient samples
Anti-Drug Antibody (ADA) ELISA
- Immunogenicity Assessment | High levels of ADAs may neutralize the therapeutic effects of the drug, rendering it less effective.
- Response Variability | Identify differences in patients response by measuring ADA levels
- Biosimilarity Evaluation | Helps to assess the immunogenicity profile of biosimilars to reference product
- Free vs. Total ADA | Acid dissociation technology breaks antibody complex making ADA detectable

FAQs - Therapeutic mAb & Biosimilar ELISA Kit
1.) How should my ELISA Kit be stored?
2.) There was a weak/no signal in my ELISA results, what could have caused this?
Possible Cause | Possible Solution |
Reagents not at room temperature | All reagents should at room temperature from the start of the assay. Room temperature should be reached following 15–20 minutes on the bench. |
Incubation time too short | Follow manufacturer guidelines in the technical manuals |
Incorrect wavelength | Manufactured kits have optimized protocols. Make sure to use recommended wavelength. Ensure plate reader is set accurately for type of substrate being used |
Target present below detection limits of assay | Decrease dilution factor or concentrate samples |
3.) Poor standard curve in results?
Reagents are poorly mixed, the standard has degraded or pipetting errors.
