Polystyrene Beads Conjugated to BSA (1 µm) – Research Use Only

Polystyrene Beads Conjugated to BSA (1 µm) are uniform 1 µm polystyrene microspheres covalently coated with bovine serum albumin (BSA). Supplied as a 1% suspension in 1 mL volume, these protein-coated beads serve as a stable, ready-to-use platform for a wide range of biochemical and immunological assays. The BSA coating provides a biocompatible surface that minimizes non-specific binding while offering functional groups for further conjugation or serving as a model protein layer in adsorption and interaction studies.

Scientific Overview

Uniform 1 µm polystyrene beads coated with bovine serum albumin (BSA) provide a well-characterized, negatively charged, protein-functionalized surface commonly used as a model system in biophysical, immunological, and cellular studies. The BSA layer serves as a blocking agent to reduce non-specific interactions and acts as a stable protein corona for investigating protein adsorption, particle–cell interactions, and microsphere-based assay development.

These BSA-conjugated polystyrene beads are suitable for:

• Protein adsorption and desorption kinetic studies
• Phagocytosis and particle uptake assays in macrophages and neutrophils
• Cell adhesion and aggregation experiments
• Flow cytometry calibration and compensation controls
• Development of microsphere-based immunoassays and multiplex arrays
• Investigation of surface chemistry effects on biological interactions

Usage & Handling Guidance

Store the 1% suspension at 2–8 °C. Do not freeze. Gently vortex or pipette up and down to ensure homogeneous resuspension before use. Avoid prolonged exposure to extreme temperatures or vigorous agitation that may cause aggregation.

• Recommended applications: Immunoassays, phagocytosis assays, protein adsorption studies, and microsphere-based platforms
• Working concentration: Dilute to desired working concentration (typically 0.01–0.1% solids) in PBS or assay buffer
• Stability: Stable when stored refrigerated; resuspend thoroughly prior to each use
• Handling: Use in a sterile environment when performing cell-based assays; compatible with standard buffers
