In the demanding fields of pharmaceutical quality control, food safety testing, and biomedical research, analyzing specific compounds like low molecular weight heparins (LMWHs), glycosaminoglycans (GAGs), or heparin-binding proteins often presents a significant challenge. These target molecules are typically buried within complex biological matrices—such as plasma, tissue homogenates, or processed products—that contain a high concentration of interfering substances like proteins, salts, and other biomolecules. Conventional sample preparation methods often fall short, leading to poor recovery, low sensitivity, and unreliable results that can compromise the entire analytical workflow, from HPLC to mass spectrometry.
Clover Technology Group, Inc. addresses this critical bottleneck with its high-performanceHeparin Immunoaffinity Columns (IAC). These columns are not simple filters; they are sophisticatedbio-specific purification tools. By leveraging the powerful and specific interaction between heparin and its binding proteins/antibodies immobilized on a robust chromatography medium, our columns achieve unparalleledselectivity, efficiency, and reproducibilityin sample cleanup. They are designed to isolate and concentrate your target analyte in a single step, transforming "dirty" samples into "analysis-ready" eluates.

The core of our technology lies inimmunoaffinity chromatography. A highly specific anti-heparin antibody (or a high-affinity heparin-binding protein) is covalently and stably immobilized onto an agarose or Sepharose gel within a user-friendly column. When a prepared sample is passed through the column:
Specific Capture:Heparin molecules (or other ligands with affinity) in the sample are selectively and tightly bound by the immobilized capture agent.
Stringent Washing:All non-specifically bound contaminants—proteins, pigments, lipids—are thoroughly washed away under optimized buffer conditions, dramatically reducing background noise.
Pure Elution:The purified target heparin (or binding protein) is then gently released using a mild, specific elution buffer, resulting in a highly concentrated and clean sample fraction.
