How do horse monoclonal antibodies differ from mouse monoclonal antibodies?

The most significant difference lies in IgG subclass diversity. Horses have 7 IgG subclasses (IgG1-IgG7) which is the most among mammals, each with distinct effector functions, whereas mice have only 4. This gives horse mAbs greater functional flexibility. Additionally, as a large mammal, the equine immune system shares more evolutionary similarity with humans.

How long does a horse mAb discovery project typically take?

Timelines vary by technology and project complexity. The phage display route typically takes 12-20 weeks from immunization to candidate antibody delivery. The single B cell sorting route can be shorter, as it bypasses the library construction step. A detailed schedule will be confirmed before project initiation.

How do I choose between phage display and single B cell sorting?

Phage display is ideal for high-throughput, large-library screening, particularly against conserved antigens or when rapid gene sequence acquisition for engineering is needed. Single B cell sorting is preferred for projects demanding native heavy-light pairing, ultra-high affinity, and rapid turnaround. Our experts will recommend the optimal route based on your antigen and objectives.

Why Choose Horse Monoclonal Antibodies?

Horses are large domesticated herbivorous mammals that have evolved the most diverse IgG constant regions among all mammals, featuring seven IgG subtypes. They mount robust immune responses and efficiently produce highly potent antibodies capable of neutralizing snake venoms and various toxins. Their large body size allows abundant blood collection at a single time point, enabling large-scale production of antibodies. As superior experimental animals for antivenom formulations and monoclonal antibody generation, they differ distinctly from small conventional immunization animals such as mice and rabbits.
