For your application

Choosing the right format

Specific IgE assays

Titre range matters more than total IgE alone — tell us your assay's detection window.

Allergen panel development

We can often supply a graded series across low to high positive if your panel needs a spread.

Calibrators

Bulk format holds titre consistency across the volume a calibrator run needs.

Cross-reactivity studies

Ask about co-sensitisation data where it's recorded — useful for interpreting cross-reactive panels.

Common questions

Before you enquire

Can you supply a graded titre series rather than a single positive lot?

Often, yes. For allergen panel development we can frequently supply a graded series across low to high positive where your panel needs a spread. Tell us what you need and we will confirm what is available.

Can I evaluate before ordering in bulk?

Often, yes. Tell us your specification and we'll confirm sample availability for your account.

Can you supply matched negatives?

Yes. Normal donor material matched on demographics is available alongside most positive lots, which is usually what validation panels need.

What about markers not listed?

We maintain donor collection relationships across multiple countries, so our reach extends well beyond what's shown here. Get in touch with your specification.

How is material shipped?

On dry ice. We prepare the export documentation your forwarder needs.
