Our portfolio began with SP1, the gold standard Estrogen Receptor (ER) marker, and has grown to over 100 SP clones available today.
Spring’s SP clone line of rabbit monoclonal antibodies continue to emerge as best-in-class immunohistochemistry markers characterized by their high affinity, sensitivity and specificity.
The proprietary recombinant rabbit monoclonal technology we utilize provides unique advantages over predecessor rabbit monoclonal approaches and legacy technologies such as mouse monoclonals. Many of these “SP” or Spring proprietary clones have subsequently risen to international prominence in their respective areas.
SP clones provide both the research and diagnostic communities with best-in-class strategic antibody biomarkers.
