In vivo Antibodies
Low endotoxin, ultra-low endotoxin and recombinant in vivo antibodies
ichorbio manufactures a broad selection of monoclonal antibodies specifically formulated for in vivo studies, available as low or ultra-low endotoxin and, for many targets, as recombinant antibodies. Antibodies are offered in mg to multi-gram quantities to support everything from pilot experiments to large preclinical studies. Each lot is tested for purity, aggregation and endotoxin, and supplied with technical and safety datasheets.
Key application area
- Immune cell depletion & modulation: CD4, CD8, CD19, Ly-6G/Ly-6C etc.
- Immune checkpoint blockade & co-stimulation: PD-1, PD-L1, CTLA-4 etc.
- Cytokines & receptors: Anti-TNFα, anti-IL-1β, anti-IFNγ, anti-IFNAR1 etc.
- Mouse immune system targeting antibodies & Fc-silenced variants

Isotype Controls - For in vivo use
Less than 1 EU/mg endotoxin | 1mg - 100mg size | >95% Purity
Isotype controls are an essential component of flow cytometry and other immunoassays. They serve as critical negative controls to distinguish nonspecific background signals from true antigen-specific binding. By matching the primary antibody’s isotype and format while lacking specificity for the target antigen, isotype controls provide the baseline needed for reliable data interpretation and gating. ichorbio manufactures a broad range of isotype controls, produced to the same low-endotoxin, preservative-free standards as their in vivo antibodies.
Highlights
- Hosts: Human, mouse, rat and hamster
- Low endotoxin & extremely low endotoxin levels – all suitable for in vivo administration
- Different variants and mutations (VHH, LALAPG, Fc plus hinge region etc.)
- Bulk sizes from 1 mg up to 100 mg off-the-shelf, with larger lots on request
Biosimilars - Research Grade (RUO)
< 1 EU/mg endotoxin | 1mg – 100mg size | >95% Purity
Biosimilars are biologic medical products that are highly similar to already approved reference products, with no clinically meaningful differences in terms of safety, purity, and efficacy.
IchorBio provides a large range of research grade (RUO) biosimilar antibodies, which are used in various research applications, including immunotherapy and drug development. They offer a range of biosimilars targeting different proteins and receptors, including immune checkpoint inhibitors like PD-1, CTLA-4, and others. These products are often used in preclinical research to study cancer, autoimmune diseases, and other conditions.
Quality and Standards: IchorBio emphasizes the production of biosimilars under stringent quality control to ensure they meet the required standards for research use. They provide detailed product specifications, including purity, endotoxin levels, and bioactivity data.

Immune checkpoint inhibitors
ichorbio’s research-grade biosimilars to immune checkpoint inhibitors (e.g. PD-1, PD-L1, CTLA-4 and additional emerging targets) enable you to closely mimic clinically relevant mechanisms of action in a RUO setting. Browse
Bispecific Biosimilars
Bispecific formats bind two different antigens or epitopes simultaneously. Evaluate target engagement, cytotoxicity and signalling in complex in vitro or in vivo systems! Browse
Antibody-drug conjugates (ADCs)
ichorbio research-grade ADC biosimilars support mechanism-of-action studies, resistance profiling and optimisation of target selection and combination partners, without consuming clinical material. Browse
Conjugated Formats
To streamline assay development, many ichorbio biosimilars are also available in directly conjugated versions (fluorophores, biotin or enzyme labels, such as e.g. APC, biotin, DyLight 488, PE, HRP etc. Browse
