Novocastra Antibodies

Create high-quality IHC slides with Novocastra primary antibodies. Developed in-house, and backed by 20 years of IHC stain development experience, these robust antibodies have been optimized for automated and manual applications. Spanning 14 pathology menus, Leica Biosystems offers laboratories a comprehensive range of clinically relevant antibodies for the most demanding workload.

Novocastra HD Antibodies

Each antibody in the Novocastra HD range has been independently evaluated1 by an external QA scheme, in comparison with two market leading vendors. Each antibody within the HD portfolio has been optimized to deliver high quality staining, for results you can trust.

Novocastra BOND RTU

BOND Ready-to-Use antibodies are optimized to deliver high quality staining results on BOND systems. This format eliminates variability that can occur with manual antibody dilutions and also reduces preparation time. Pre-optimized reagents and automated protocols deliver consistent results you can depend on.

Novocastra Liquid Concentrates

The Novocastra liquid concentrated antibody range is an extensive collection of primary antibodies for IHC testing. Concentrated antibodies afford workflow flexibility, enabling users to optimize their protocols according to their pre-analytical conditions2.

Reducing our Paper Waste by 95%*

In a bid to support environmental sustainability, in 2019 Leica Biosystems’ elected products will transition from printed and packaged IFUs to eIFUs (electronic instructions for use). These eIFUs will be available for download within their respective product pages within this website.


IHC reagents including detection systems, antibodies and ancillaries.

Please email LBSNEW-IFU@leicabiosystems.com if support is required.

Did You Know?

On average, each elected product is packaged with around 20 printed pages of instructions for use (IFU). Leica Biosystems aims to reduce this number to 1 printed page, resulting in a 95% reduction of paper waste.

*Territories that do not accept eIFU will still receive a compatible physical IFU
