Vector Laboratories Cross-Linkers &
DSPE Linkers

Now Available through SZABO-SCANDIC in Austria

We are expanding our Specialty Chemistry & Bioconjugation portfolio.

SZABO-SCANDIC is now the official distributor in Austria for Vector Laboratories’ cross-linkers, dPEG® linkers, DSPE linkers, and click chemistry reagents.

These tools enable highly controlled, bioorthogonal conjugation workflows across academia, diagnostics, and biopharma.

Precision Bioconjugation Starts with the Right Chemistry

Modern life science workflows increasingly rely on:

• Targeted antibody conjugates
• Lipid-functionalized nanoparticles
• ADC & AOC development
• Protein and oligonucleotide labeling
• Multiplex assay systems

Vector’s chemistry portfolio is designed to support these applications with reproducibility, modularity, and scalability.

Why Click Chemistry?

Click chemistry has become a cornerstone of modern conjugation strategies, offering:

• Bioorthogonality – No interference with biological systems
• High specificity – Minimal off-target reactions
• Fast reaction kinetics – Seconds to minutes
• High efficiency – Excellent yields
• Scalability – From R&D to production

Key reactive groups include:

Azide • Alkyne • DBCO • TCO • Tetrazine

Major Click Chemistry Platforms

CuAAC – Copper-Catalyzed Click Chemistry

Ideal for in vitro applications requiring highest efficiency.
Excellent yields and broad substrate compatibility.
Limitation: Copper toxicity restricts live-cell use.

SPAAC / DBCO – Strain-Promoted Click Chemistry

Copper-free and therefore suitable for live-cell and in vivo applications.
Biocompatible and modular.

IEDDA – Tetrazine-TCO Chemistry

Ultra-fast kinetics (up to 10⁶ M⁻¹s⁻¹) for rapid conjugation and in vivo workflows.

dPEG® Linkers – The Hidden Key to Conjugate Performance
