Singer MSM 400 Yeast Micromanipulation System

Overview

The Singer MSM 400 Yeast Micromanipulation System is a purpose-built, fully integrated workstation engineered exclusively for precision micromanipulation of yeast cells—including Saccharomyces cerevisiae, Schizosaccharomyces pombe, and other model yeasts. Unlike general-purpose micromanipulators, the MSM 400 implements a closed-loop, motorized optical-mechanical architecture optimized for tetrad dissection, spore isolation, mutant screening, lifespan assays, and clonal colony picking. Its core operational principle combines high-resolution transmitted-light microscopy with sub-micron XY-stage positioning (4 µm resolution, 2 µm repeatability), real-time visual feedback via a calibrated wide-field imaging path, and deterministic mechanical actuation of calibrated glass or tungsten microneedles. Designed in close collaboration with leading yeast genetics laboratories worldwide, the system adheres to fundamental biophysical constraints of yeast cell handling—minimizing shear stress, avoiding desiccation, and preserving viability during prolonged manipulation sessions.

Key Features

• Integrated inverted microscope platform with Singer ×4, ×20, and XLWD plan-apochromatic objectives and ×15 wide-field eyepieces
• Motorized XYZ stage with 4 µm positional resolution and 2 µm repeatability; compatible with Singer PlusPlates®, ANSI/SBS-standard multiwell plates, standard Petri dishes, and glass slides
• Dedicated, low-vibration micromanipulator mounted on either left or right side; dual-axis control (horizontal lever + coaxial vertical ring) for intuitive needle positioning
• LED white-light illumination (5000-hour lifetime, adjustable intensity) with under-stage annular window to eliminate airborne contamination during plate loading
• 400-series touchscreen controller featuring 80 GB SSD storage, 1 GB RAM, WPA2-secured Wi-Fi, and full-color GUI with real-time coordinate overlay and mode status indicators
• Ergonomic dual-hand operation: one hand controls stage navigation via joystick; the other manipulates needle position—both supported comfortably at desktop height
• Auto-reset capability for microneedles via software command; reversible tray orientation to prevent agar drying and surface contamination

Sample Compatibility & Compliance

The MSM 400 supports standardized microbiological substrates including Singer PlusPlates® (proprietary high-density tetrad arrays), 96- and 384-well SBS-compliant plates, standard 100 mm Petri dishes, and conventional glass slides. Its workflow design aligns with Good Laboratory Practice (GLP) principles: all manipulations are traceable via timestamped image capture, stage-coordinate logging, and user-defined protocol naming. While not certified as medical device hardware, the system’s architecture enables compliance with ISO/IEC 17025 requirements for method validation in academic and industrial yeast genetics labs. The LED illumination meets IEC 62471 photobiological safety standards for Class 1 light sources.

Software & Data Management

The MSM 400 runs proprietary firmware with an embedded Linux-based OS. All imaging, stage movement, and needle actuation events are logged with microsecond-level timestamps and stored locally on the onboard SSD. Image sequences—including time-lapse acquisitions for germination or aging assays—are saved in lossless TIFF format with embedded metadata (objective magnification, stage coordinates, user ID, date/time). Remote diagnostics and secure firmware updates are delivered over WPA2-encrypted Wi-Fi. Audit trails support retrospective review per GLP/GMP-aligned documentation practices. Export options include CSV (coordinate logs), TIFF (images), and XML (protocol definitions) for integration into LIMS or ELN environments.

Applications

• Tetrad dissection and spore isolation in S. cerevisiae genetic crosses
• Clonal isolation of mutants from mutagenesis screens or CRISPR-Cas9 editing workflows
• Single-cell picking for lifespan analysis, replicative aging assays, and mother–daughter separation
• High-fidelity colony transfer for strain banking, cross-streaking, and mating-type verification
• Preparation of defined yeast arrays for phenotypic profiling, drug sensitivity testing, or synthetic genetic array (SGA) analysis
• Microinjection support (with optional needle calibration kits) for cytoplasmic or nuclear delivery in large-budded cells

FAQ

Is the MSM 400 suitable for non-yeast microbial species?
The system is mechanically and optically optimized for yeast morphology (5–10 µm diameter, spherical/ovoid shape, rigid cell wall). While some filamentous fungi or large bacteria may be handled with modified protocols, it is not validated for bacterial colonies, mammalian cells, or plant protoplasts.
Does the MSM 400 comply with FDA 21 CFR Part 11?
The system does not include electronic signature functionality or role-based access control required for Part 11 compliance; however, its audit-trail-capable logging infrastructure serves as a foundation for lab-specific validation under internal SOPs.
Can third-party microscopes be integrated?
No—the MSM 400 is a monolithic, factory-calibrated platform. Objective lenses, stage mechanics, and image processing pipelines are co-engineered and not interoperable with external microscope bodies.
What maintenance is required for long-term reliability?
Annual recalibration of stage encoders and optical alignment is recommended. Needle holders and stage bearings require cleaning every 6 months using isopropyl alcohol and lint-free wipes; no lubrication is necessary.
Is training included with purchase?
Yes—Singer provides remote onboarding, live virtual workshops, and access to an online knowledge base with video-guided SOPs, troubleshooting trees, and downloadable protocol templates.
