Related Mechanisms, Research Methods and Product Applications

1. Anti-GFP Nanobody Beads: Mechanism, Superiority and Core Applications

Core Mechanism of Affinity Capture

ANT BIO PTE. LTD.’s Anti-GFP Nanobody Beads leverage ~15 kDa camelid-derived single-domain nanobodies covalently conjugated to agarose/magnetic agarose matrices. The nanobodies bind with ultra-high specificity and affinity to the native conformation of GFP and its variants (EGFP, YFP), forming stable complexes that withstand mild washing. Bound proteins are eluted via gentle strategies (low pH, GFP peptide competition) that preserve native protein structure and activity—enabling purification of GFP-tagged proteins and their associated complexes from complex cell lysates.

Superiority Over Traditional Antibody Beads

Core Applications

• Co-Immunoprecipitation (Co-IP): Capturing GFP-tagged "bait" proteins and their native "prey" binding partners to identify novel protein-protein interactions.
• Native protein affinity purification: One-step purification of active GFP-tagged proteins from mammalian/yeast/bacterial lysates for biochemical assays and structural biology.
• GFP-ChIP: Isolating GFP-tagged protein-chromatin complexes to map genome-wide DNA binding sites for transcription factors and chromatin modifiers.
• Organelle-specific complex isolation: Enriching GFP-tagged protein complexes from mitochondria, ER and nucleus via subcellular fractionation and bead capture.
• Membrane protein purification: Solubilizing and capturing GFP-tagged membrane proteins in mild detergents to preserve native oligomeric states and binding partners.

2. Cell Sorting Magnetic Nanobeads: Mechanism, MICS Technology and Core Applications

Core Mechanism of Immunomagnetic Cell Sorting (MICS)

MICS technology, powered by ANT BIO PTE. LTD.’s Cell Sorting Magnetic Nanobeads, combines immunomagnetic labeling and microfluidic chip separation:

1. Nanobead labeling: Superparamagnetic nanobeads conjugated to target-specific antibodies bind to cell surface antigens, with bead number proportional to antigen expression level.
2. Microfluidic separation: Labeled cells flow through a microfluidic chip with precision magnetic field generators; magnetic forces deflect bead-labeled cells, separating them into subpopulations (high/low/baseline antigen expression) based on preset magnetic thresholds—processing millions of cells simultaneously.

MICS vs. Traditional FACS: Key Advantages

1. Ultra-high throughput: Processes billions of cells per hour, scalable via multi-chip parallel operation for genome-wide CRISPR screening.
2. Superior cell viability: Enclosed microchannel sorting avoids sheath fluid pressure, laser exposure and electrical charges, preserving cell function and recovery.
3. Cost & operation efficiency: Eliminates complex laser/photomultiplier systems; high throughput shortens experimental cycles and reduces per-cell sorting costs.

Core Applications

• Immune cell functional research: Isolating high-purity CD8+/CD4+/CD3+ T cells and CD14+ monocytes for in vitro activation, proliferation and killing activity assays.
• Tumor immunology research: Purifying tumor-infiltrating lymphocytes (TILs) from tumor tissue for studying anti-tumor immune responses.
• CRISPR screening for target discovery: Sorting phenotype-specific cell populations from CRISPR-edited cell pools to identify genes regulating disease-related traits (e.g., CD47 expression).
• Infection/autoimmune disease research: Enriching antigen-specific immune cells from disease models to study immune response kinetics and memory formation.
• Cell therapy sample preparation: Isolating high-purity engineered immune cells for CAR-T/TIL preclinical development and testing.
