Technical & Manufacturing FAQs
What exactly is a research-grade biosimilar?
A research-grade biosimilar is a recombinant antibody engineered to have the identical variable region sequence as a therapeutic drug. They are strictly for research use only (RUO) but are designed to behave identically to the commercial drug in preclinical models, ensuring consistent target engagement.
What are your quality control standards for biosimilars?
Every product undergoes rigorous lot-specific testing. We guarantee >95% monomeric purity as determined by SEC-HPLC and SDS-PAGE. For in vivo applications, our antibodies are tested using the LAL method to ensure ultra-low endotoxin levels (<0.1 EU/µg).
Can I request specific formats or custom isotypes?
Yes. To avoid unwanted immune responses or off-target effector functions (ADCC/CDC) in animal models, we can facilitate custom biomanufacturing. This includes providing mouse-matched chimeric backbones or specific Fc-silenced variants (like IgG4 S228P or LALA-PG). Please use our enquiry form for specialized requests.
What is the timeline for bulk orders and lot reservations?
For available catalog items, bulk quantities from 100µg up to 200mg can typically be dispatched within 5-6 weeks. We strongly recommend discussing your timeline with our procurement team to ensure seamless lot reservations for longitudinal studies.
Are these antibodies suitable for in vivo animal models?
Yes. Most of our biosimilars are suitable for In Vivo use and are formulated without carrier proteins or preservatives (BSA-free, Azide-free) and are tightly controlled for endotoxins, preventing unwanted systemic inflammation or immune responses in murine hosts.
