## Long description

## Overview

Vipergen specializes in DNA-encoded library (DEL) screening services for accelerating hit identification in early-stage drug discovery. The company has been focused on DNA-encoded library synthesis and screening since 2005.

## Core Services

Vipergen offers flexible DEL screening packages:

- **DEL Snap**: Fast, affordable early lead identification for startups (20 business days; requires biotinylated protein)
- **DEL Express**: Hit list and structures for tractable targets with purified protein (20 business days)
- **DELs in Cells Snap**: Early lead discovery using amino acid sequence input (40 business days)
- **DELs in Cells Express**: Hit identification without purified protein requirement (30 business days)
- **Custom DEL Screen**: Bespoke campaigns for difficult targets including molecular glues, protein-protein interactions, transcription factors, and membrane proteins
- **Custom DEL in Cells Screen**: In-cell screening for challenging targets

## Key Differentiators

- **High-fidelity libraries (yoctoReactor)**: Constructed without truncates and with 100% barcode-to-compound correspondence, improving hit validation rates
- **Massive chemical space**: Each library contains 500+ million drug-like molecules screened in single experiments
- **Multiple screening formats**: Binder Trap Enrichment (BTE) for homogeneous in vitro selections and cellular BTE (cBTE) for screening inside living cells
- **Reduced barriers to entry**: cBTE eliminates the need for highly purified target protein and broadens accessible target space
- **Actionable outputs**: Ranked hits with chemical structures and data designed to accelerate medicinal chemistry decisions

## Commercial Models

Vipergen offers flexible engagement structures:

- **Fee-for-Service (standard)**: DEL screening with optional off-DNA resynthesis
- **Collaborative models**: Extended hit-to-lead partnerships where appropriate

## IP & Ownership

- Client owns program-specific data and validated compounds generated for their target
- Vipergen retains background IP related to platform technologies, library design, and methods
- Client owns foreground IP for nominated chemical series with no downstream financial obligations
