You can request preimmune bleeds from a group of animals, and we'll provide up to 14 days of daily maintenance time for you to evaluate the bleeds and choose the most suitable candidates for antibody production. We charge a flat rate per animal, which includes the bleed and maintenance time, plus shipping costs.

To make the most of this service, it's essential to have your screening methodologies ready beforehand to avoid delays and additional fees. We recommend requesting three prescreening animals for every one you plan to use for antibody production, ensuring you have sufficient options to choose from.

To get started, simply submit a Client Information Form and contact us with the species and number of animals you wish to screen. Once you've selected the animals for antibody production, we'll only charge setup fees for those chosen candidates.

With our Preimmune Bleed Prescreening service, you can confidently select the best-suited animals for your antibody production project, setting the stage for success from the very beginning.
