●Monoclonal Antibodies

Ichorbio offers monoclonal antibodies with high specificity and lot-to-lot consistency for research use. These antibodies undergo strict quality control and are designed to recognize defined target epitopes with reliable performance in applications such as immunodetection, flow cytometry, and other antibody-based assays, helping researchers investigate target protein expression and function with greater confidence. Official site navigation lists Monoclonal Antibodies as a standalone product category. 

●Recombinant Antibodies

Ichorbio’s recombinant antibodies are produced using engineered expression systems to provide stable performance, reproducibility, and flexible design options. These reagents are well suited for complex experimental systems and can support drug discovery, mechanism-of-action studies, and translational research where defined sequence, consistent quality, and scalable production are important. The official website lists Recombinant Antibodies as a major product line and notes their suitability for in vivo research applications. 

●Recombinant Proteins

Recombinant proteins from Ichorbio are intended to support biopharmaceutical research, screening studies, and functional characterization workflows. Produced using controlled expression and purification processes, these proteins are designed to provide the purity and activity required for demanding laboratory applications, including ligand-binding studies, pathway analysis, and assay development. Recombinant Proteins are listed by Ichorbio as one of its core product categories.

●Tag Antibodies

Ichorbio provides tag antibodies for the detection of fusion proteins carrying commonly used tags. These products help researchers rapidly and accurately identify tagged targets during protein expression, purification, and interaction studies, making them useful tools for routine protein biology workflows as well as assay optimization. The official website includes Tag Antibodies as a dedicated product category. 

●Buffers

Ichorbio also offers auxiliary reagents, including buffer products that help maintain stable experimental conditions in antibody handling and related biological workflows. These reagents are designed to support consistent assay performance and reliable sample preparation across research applications. The official website groups these supporting products under Auxiliary Reagents. 

●In Vivo Antibodies

Ichorbio is particularly focused on providing high-quality in vivo antibodies for animal studies. These antibodies are specially prepared to offer low immunogenicity, high stability, and low endotoxin performance, making them suitable for studies of antibody distribution, pharmacology, immune modulation, and therapeutic activity in vivo. Official product information highlights low-endotoxin and ultra-low-endotoxin in vivo antibodies, with batch testing for purity, aggregation, and endotoxin, and availability from milligram to multi-gram scale for preclinical research. 

●Isotype Controls

Ichorbio provides isotype controls for human, mouse, rat, hamster, and other experimental systems. These controls are essential for distinguishing specific antigen recognition from non-specific background in flow cytometry and other immunoassays. By matching the immunoglobulin subtype of the primary antibody without recognizing the target antigen, isotype controls help establish appropriate baselines and improve the accuracy and interpretability of experimental results. Official company materials describe isotype controls as an important part of validated in vivo research workflows. 

●Research Biosimilars

Ichorbio develops research-grade biosimilars, including bispecific antibodies and other advanced therapeutic formats, to support studies in cancer, immunotherapy, and autoimmune disease. This category is useful for evaluating clinically relevant targets, modeling the activity of approved therapeutic antibodies, and exploring new treatment strategies.
