Agilent AssayMAP Bravo Protein Sample Preparation Platform

Overview

The Agilent AssayMAP Bravo Protein Sample Preparation Platform is an automated, microscale chromatography-based liquid handling system engineered for reproducible, high-throughput protein and peptide sample preparation. Unlike conventional magnetic bead–based workflows, the AssayMAP Bravo employs precision fluidic control coupled with resin-packed microcolumns (AssayMAP cartridges) to perform solid-phase extraction (SPE), affinity capture, desalting, phosphopeptide enrichment, immunoaffinity purification, and other critical front-end processing steps. Its core principle relies on controlled laminar flow through defined resin beds—minimizing diffusion distances and maximizing binding kinetics for large biomolecules such as intact proteins, antibodies, and ADCs. Designed specifically for proteomics, biopharmaceutical characterization, and multi-omics research, the platform bridges the gap between manual benchtop protocols and regulated analytical environments by integrating hardware robustness, method traceability, and software-controlled workflow execution.

Key Features

• Precision liquid handling architecture delivering sub-microliter dispensing accuracy and low carryover across 96- and 384-well formats
• Modular microcolumn support for multiple resin chemistries (e.g., C18, SCX, TiO₂, Protein A/G, immobilized metal affinity chromatography [IMAC], custom functionalized resins) in standardized 10–200 µL bed volumes
• Pre-validated, protocol-driven software interface with drag-and-drop workflow builder and parameter locking for method standardization
• User-accessible permission levels (Operator, Supervisor, Administrator) enabling role-based access control and audit-ready operation
• Integrated compliance features including electronic signatures, audit trails, and 21 CFR Part 11–ready configuration options for GxP environments
• Seamless interoperability with downstream Agilent LC/MS systems and Evosep One nanoLC platforms via Evotip Pure tip loading modules

Sample Compatibility & Compliance

The AssayMAP Bravo accommodates a broad range of biological matrices—including cell lysates, serum, plasma, tissue homogenates, and purified monoclonal antibody preparations—without requiring method redevelopment. Its microcolumn format ensures consistent binding capacity and elution efficiency across sample types, supporting both discovery-scale and targeted quantitative workflows. The platform complies with ISO/IEC 17025 requirements for testing laboratories and supports alignment with ICH Q5, Q6, and Q7 guidelines for biopharmaceutical quality attributes. When configured with compliant software settings, it meets FDA 21 CFR Part 11 criteria for electronic records and signatures, enabling transfer of validated methods from non-regulated discovery labs into GLP- or GMP-compliant QC/QA settings without requalification.

Software & Data Management

The AssayMAP Bravo Control Software provides a Windows-based graphical interface with built-in method library management, real-time run monitoring, and automatic log generation. Each executed step—including aspiration volume, flow rate, incubation time, wash cycles, and elution parameters—is timestamped and recorded in an immutable audit trail. Raw log files are exportable in CSV or XML format for integration into LIMS or ELN systems. Version-controlled method templates allow cross-lab deployment while preserving integrity of original validation data. Software updates follow Agilent’s formal change control process, documented per ISO 9001 and aligned with computerized system validation (CSV) best practices.

Applications

• Characterization and quantitation of therapeutic proteins, including mAbs, bispecifics, and fusion proteins
• Phosphoproteomics enrichment for kinase pathway analysis and target engagement studies
• Immunopeptidomics workflows for HLA-bound peptide isolation and neoantigen discovery
• ADC drug–antibody ratio (DAR) analysis and payload release profiling
• Biomarker verification using targeted MRM or HRAM workflows on Agilent 6495C or 6545XT systems
• Multi-omic sample prep harmonization across proteomics, metabolomics, and glycomics pipelines
• PK/PD sample processing for preclinical and clinical bioanalysis under regulated conditions

FAQ

Can the AssayMAP Bravo be used in a 21 CFR Part 11–compliant environment?
Yes—when deployed with compliant software configuration, electronic signature modules, and documented system validation, it supports full adherence to 21 CFR Part 11 requirements.
What column formats and resin types are supported?
Standardized AssayMAP cartridges in 10 µL, 30 µL, 100 µL, and 200 µL bed volumes; compatible with C18, SCX, TiO₂, IMAC, Protein A/G, anti-FLAG, and custom functionalized resins.
Is method transfer possible between non-regulated and regulated labs?
Yes—the platform enables direct migration of pre-validated protocols between discovery and GxP settings using identical hardware, software logic, and cartridge specifications.
How does it compare to magnetic bead–based automation?
AssayMAP microcolumns offer shorter diffusion paths, higher binding capacity per unit volume, reduced nonspecific binding, and superior reproducibility in low-input applications compared to bead suspensions.
Does Agilent provide application support and method development assistance?
Yes—Agilent offers application notes, peer-reviewed protocol libraries, and technical support services including on-site method optimization and IQ/OQ documentation packages.
