GMP ActiveMax® Streptavidin μBeads

This product can be directly isolated using conventional column-free magnetic stand (eg. Cat. MB-01/ MB-02/ MB-03/ MB-04). Please note that due to its micron-scale size, it is not compatible with commercially available column-based (M/D/L) magnetic separation systems.

• Core Technical Advantages
  • No separation columns required, magnetic stand enables fast post-culture bead-cell separation
  • No internalization risk, 5.5μm beads resist cellular uptake, protecting cell metabolism and function
  • Directly conjugate to biotinylated antibodies/proteins for cell sorting, activation, and expansion
  • Premium Grade (Pre-GMP) and GMP versions offer identical performance for seamless R&D to manufacturing transition
• Compliance & Manufacturing Assurance
  • Designed under ISO 9001:2015 and ISO 13485:2016
  • Manufactured and QC tested under a GMP-compliant factory
  • Stringent quality control tests
• Material & Quality Attributes
  • Animal-Free materials
  • Beta-lactam materials free
  • Batch-to-batch consistency
  • GMP-grade recombinant HSA as an excipient

GMP ActiveMax® Streptavidin μBeads are uniform, superparamagnetic beads of 5.5 µm with streptavidin on their surface. Streptavidin is a tetrameric protein that provides four high-affinity biotin binding sites, making it possible to quickly prepare and customize your own sterile protein/antibody-coupled beads for cell-based assays, cell sorting, cell therapy process development, and manufacturing use.
GMP ActiveMax® Streptavidin μBeads are manufactured under a GMP-compliant factory with animal-free raw materials and tested under GMP guidelines.

GMP ActiveMax® Streptavidin μBeads can be used for coupling of any biotinylated proteins or antibodies, and are ideal for numerous applications as follows:
When coupled with biotinylated CAR target proteins, it can be used to stimulate or isolate CAR-T cells or UCAR-T cells.
When coupled with biotinylated antibodies, it can be used to isolate antigen-specific cells, including immune cells and tumor cells, etc.
When coupled with biotinylated drug targets, it can be used for screening target specific antibodies by FACS.
It can also be used for other cell-based experiments that you need.
