Genlantis EZ Spread Plating Beads

Genlantis C400100 EZ-Spread™ Plating Beads (Sterile, Glass)

The Genlantis C400100 EZ-Spread™ Plating Beads provide a rapid, efficient, and standardized method for the uniform distribution of bacterial or yeast cells across the surface of agar plates. Eliminating the need for traditional spreaders or "hockey sticks," these 4 mm glass beads utilize simple mechanical shaking to achieve a perfectly even lawn of colonies. This method significantly reduces the time spent per plate and minimizes the risk of cross-contamination by eliminating the need for flame-sterilization between samples. The EZ-Spread™ beads are an essential tool for high-throughput cloning, transformation, and screening workflows where consistency and speed are paramount.

Technical Performance and Design

• Uniform Colony Distribution: The rolling action of the beads across the agar surface ensures a more consistent distribution of cells compared to manual spreading, leading to more accurate colony counts and better-isolated colonies.

• Contamination Control: As a "touch-free" method, these beads reduce the exposure of the plate to the environment. The beads are provided pre-sterilized and ready for immediate use in the biosafety cabinet or on the benchtop.

• High-Throughput Efficiency: Multiple plates can be processed simultaneously by stacking them and shaking, allowing a researcher to plate dozens of samples in a fraction of the time required for traditional methods.

• Gentle Mechanical Action: The 4 mm glass spheres provide just enough weight to spread the liquid inoculum without tearing or gouging the agar surface, preserving the integrity of the growth medium.

Product Specifications

Key Benefits & Applications

• Bacterial Transformation: The gold standard for plating competent cells following transformation with plasmid DNA (e.g., E. coli protocols).

• Yeast Genetics: Ideal for spreading S. cerevisiae or P. pastoris cultures for library screening or phenotypic analysis.

• Blue/White Screening: Provides the evenness required for clear visualization of colorimetric markers across the entire plate surface.

• Laboratory Standardization: Removes "user-to-user" variability in plating technique, ensuring that every plate in a study is treated identically.
