Triple Point Biologics' Superpooled Kits antibody catalog covers domain-pooled rabbit polyclonal antibody mixtures in which two or more epitope-specific antibodies, each raised against a distinct, non-overlapping region of the same target protein, are combined into a single ready-to-use reagent. This format addresses a well-documented limitation of single-epitope antibodies: when a target is expressed at low abundance, is subject to alternative splicing, or carries post-translational modifications that mask individual epitopes, a single antibody clone may yield inconsistent or absent signal. By directing immune recognition at multiple domains simultaneously, a superpooled reagent distributes binding probability across the full-length protein, improving detection reliability without requiring the researcher to optimize and validate multiple antibody lots independently. Each component antibody in a kit is raised in rabbit and produced as a polyclonal, preserving the epitope diversity inherent to the polyclonal format while adding the deliberate, domain-level architecture of the pool design.

Triple Point Biologics has produced proteinase and inhibitor-focused antibody reagents since 1994, and the Superpooled Kits collection reflects that depth of target coverage. Each kit is validated for Western blot detection across the relevant molecular weight range of the target, with selected kits carrying additional validation data for immunohistochemistry (IHC) and immunofluorescence (IF); cross-reactivity with non-target species is reported as validated or predicted based on sequence homology, not assumed. Every target in the Superpooled Kits catalog is matched to a recombinant protein antigen produced in-house from the same laboratory, providing a structurally defined positive control for signal confirmation. Details on our validation standards and lot-release criteria are described on the Quality and Validation page, and the matched recombinant proteins are available through the Recombinant Proteins catalog.

Superpooled Kits are suited to applications where comprehensive domain coverage is a methodological requirement: co-immunoprecipitation experiments targeting proteins with structured, independently folded domains; Western blot detection of isoforms that differ in their N- or C-terminal sequences; and signal amplification for low-abundance endogenous targets in tissue lysates or FFPE sections. Researchers screening protease inhibitor candidates or profiling protease activity in complex biological matrices may find the isoform-agnostic detection profile particularly useful; relevant experimental frameworks are outlined in the Protease Activity Assays and Protease Inhibitor Screening guides.
