Tosoh AIA-PACK Substrate Set II – AIA-360 / 900 / 2000 Immunoassay Analyzers (Cat. No. 0020968)

What is it:

The Tosoh AIA-PACK Substrate Set II (Cat. No. 0020968) is a genuine Tosoh system reagent for the AIA line of automated immunoassay analyzers. It's the enzyme-substrate system used across the AIA-PACK assay menu, supplied as a set of substrate reagent plus reconstituent (2 × reagent, 2 × 100 mL reconstituent). For professional in vitro diagnostic use.

Part number:

• Cat. No. (REF): 0020968

Also searchable as (previous Tosoh part numbers):

• 020968
• 20968

What it's used for:

The Substrate Set II provides the enzyme substrate that generates the measurable signal in the Tosoh AIA immunoassay reaction. The AIA-PACK assays use an enzyme-labeled system, and this substrate is what that enzyme acts on to produce the fluorescent signal the analyzer reads — so it's fundamental to every measurement the instrument makes. Because it's a shared reagent required across the AIA-PACK menu rather than tied to a single analyte, it's one of the core consumables an AIA lab reorders routinely. The set pairs the substrate reagent with its reconstituent, which are prepared together before use.

What's included:

• 2 × AIA-PACK Substrate Reagent II
• 2 × 100 mL AIA-PACK Substrate Reconstituent II
• Genuine Tosoh AIA-PACK system reagent
• Manufactured by Tosoh Corporation

Compatible analyzers:

• Tosoh AIA-360
• Tosoh AIA-600 II
• Tosoh AIA-900
• Tosoh AIA-1800
• Tosoh AIA-2000

This is a shared AIA-PACK system reagent for Tosoh AIA immunoassay analyzers. Confirm it matches your analyzer's reagent requirements if you're unsure. Not for use with non-Tosoh instruments.

FAQs:

What is the Tosoh AIA-PACK Substrate Set II used for?

It provides the enzyme substrate that generates the fluorescent signal in the Tosoh AIA immunoassay reaction. It's a shared system reagent used across the AIA-PACK menu, so it's required for essentially every assay the analyzer runs and is reordered routinely.

What's in the set?

The set includes the AIA-PACK Substrate Reagent II plus 2 × 100 mL of Substrate Reconstituent II, which are prepared together before use. Follow the package insert for reconstitution and on-board stability.

Which analyzers is Cat. No. 0020968 compatible with?

The Tosoh AIA family — AIA-360, AIA-600 II, AIA-900, AIA-1800, and AIA-2000. If you're unsure whether it fits your specific configuration, send us your analyzer model and we'll confirm.

Does it need refrigeration?

Yes. Store refrigerated at 2–8°C, and the product ships with cold-chain handling.
