Our Carrier-Free antibodies are formulated in PBS without BSA or Azide.
Antibodies Inc.'s Carrier-Free antibodies offer key advantages, including increased sensitivity, lower background, and enhanced versatility. Without carrier proteins like BSA, labeling efficiency improves, maximizing assay sensitivity for low-abundance targets. They also reduce non-specific binding, leading to cleaner signals. Carrier-free antibodies are ideal for bioconjugation, as they eliminate preservatives like sodium azide that interfere with labeling. This makes them particularly valuable in multiplexing applications such as mass and flow cytometry, where precise conjugation is essential for distinguishing multiple targets.
