What sets ichorbio apart?
Researchers working with live models require antibodies that meet far stricter criteria than those used for in vitro applications. ichorbio stands out by offering:
- Low, Ultra-low, and Extremely-low Endotoxin Antibodies – Ensuring minimal immune activation.
- High Purity Standards – With antibodies routinely tested for ≥95% or even ≥98% purity via SDS-PAGE and HPLC.
- Batch-to-batch Consistency – Critical for reproducibility across long-term studies.
- In Vivo Validation – Including dosage recommendations, administration routes, and data-backed performance insights.
In Vivo Antibodies
ichorbio’s in vivo antibodies are specifically optimised for use in live animal models, where precision, consistency, and safety are critical. These antibodies are available in a range of endotoxin grades to best suit the sensitivity of various research endeavours.
- Low endotoxin (<1 EU/mg, >95% purity) — Suitable for most immunological studies and tumour models.
- Ultra-low endotoxin (<0.5 EU/mg, >98% purity) — Ideal for models requiring reduced background activation.
- Extremely low endotoxin (<0.05 EU/mg) — Available for selected clones, supporting the most stringent preclinical protocols.
Each batch undergoes rigorous analytical validation, including SDS-PAGE, HPLC, dynamic light scattering, and size-exclusion chromatography to confirm purity and aggregation profiles. Overall ensuring that researchers can depend on their biological activity, biodistribution, and performance in vivo.
