For your application

Choosing the right format

Assay development

Start with a residual clinical sample to confirm specificity before committing to a bulk order.

Calibrators and controls

Bulk format gives lot-to-lot consistency at the titre your standard curve needs.

Validation panels

Matched negatives are available alongside most positive lots for the panel you're likely building.

Platform comparison

Ask for lots with results on more than one platform if your comparison needs cross-platform data.

Common questions

Before you enquire

Can I get results on more than one platform for a single lot?

For platform comparison work, ask when you enquire — we can check which lots have results recorded on more than one platform.

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.
