LGC·SeraCare·KPL (hereinafter referred to as KPL), distributed by XMJ, is a world-renowned manufacturer of commercially available affinity-purified secondary antibodies and substrate chromogenic systems. With over 40 years of product R&D experience, KPL has obtained ISO 13485 quality management system certification. Its products feature consistent batch-to-batch performance and reliable quality, earning high recognition and praise from numerous diagnostic companies.

KPL’s product portfolio includes cost-effective secondary antibodies, substrate chromogenic reagents, and immunoassistive reagents, which are widely used in fields such as immunological research, diagnostic reagent development, and clinical testing. This article will focus on introducing KPL’s secondary antibody product series.

KPL - High-Cost-Performance Secondary Antibodies

l Comprehensive Species Coverage: KPL’s secondary antibodies cover more than 20 species. The main species include human, rabbit, mouse, rat, goat, sheep, horse, cow, monkey, pig, cat, chicken, guinea pig, and hamster. Among them, secondary antibodies for special species include duck, deer, and white-footed mouse.

l High Dilution Ratios

ü For enzyme-conjugated (HRP/AP) secondary antibodies: The recommended dilution ratio is 1:5000–20000 in Western Blot (WB) experiments.

ü For general fluorescent (FITC/TRITC) secondary antibodies: The recommended dilution ratio is 1:100 in immunofluorescence (IF)/immunocytochemistry (ICC) experiments.

ü For DyLight series fluorescent secondary antibodies: The recommended dilution ratio is 1:100–1000 in IF/ICC experiments.

l Rich Antibody Isotypes: A variety of antibody isotypes are available, including IgA (α), IgE (ε), IgG (γ), IgM (μ), Ig (H+L), IgG (Fc), and IgA+IgG+IgM. In addition, secondary antibodies of F(ab’)? Fragments are also provided to meet diverse detection needs.

l High Specificity: The antigens used for antibody preparation and the immunized animals undergo strict screening. The obtained antibodies are processed through steps such as salt precipitation, antigen-affinity purification, multi-species serum adsorption, and multiple detection tests. These processes significantly reduce cross-reactivity and ensure high specificity.

l Long Shelf Life: All secondary antibodies feature high purity, high signal-to-noise ratio, strong specificity, and consistent batch-to-batch performance. With a long shelf life, they can be stored stably for more than 1 year.

l Fluorescent Secondary Antibodies: In addition to traditional enzyme-conjugated and fluorescent secondary antibodies, KPL also offers DyLight series fluorescent secondary antibodies. This series exhibits stronger fluorescence intensity, higher sensitivity, better anti-bleaching performance, and longer-lasting luminescence, making it suitable for fluorescence imaging. Its high signal-to-noise ratio and low background characteristics enable excellent performance in various detection platforms, including immunohistochemistry (IHC), flow cytometry, Western Blot, protein microarrays, and fluorescent-linked immunosorbent assay (FLISA). It is also compatible with various buffer systems with a pH range of 4–10.

With their outstanding performance and diverse options, KPL’s secondary antibody product series has become the preferred brand in the fields of immunological research and diagnostic reagent development. Whether it is cost-effective enzyme-conjugated and fluorescent secondary antibodies, or the DyLight series fluorescent secondary antibodies with unique advantages, KPL can provide users with reliable solutions to facilitate the smooth progress of scientific research and diagnostic work.

KPL (Kinetic Plasmonics Laboratories) is a company with a profound history and an outstanding reputation in the biological sciences field. As one of the world’s early biotechnology companies to commercialize affinity-purified secondary antibodies, KPL has laid a solid foundation for development by virtue of its pioneering position in this field. Additionally, KPL is also one of the world’s largest manufacturers of secondary antibodies and substrate chromogenic systems. It boasts nearly 40 years of product R&D experience, accumulating extensive professional knowledge and technical capabilities.

The company has obtained ISO 13485 quality management system certification, ensuring minimal batch-to-batch variation and reliable quality of all products. KPL’s products are characterized by high purity, high sensitivity, and a high signal-to-noise ratio (strong signal, low background), earning the trust of researchers and diagnostic enterprises alike.

In 2013, KPL was acquired by SeraCare, a supplier of in vitro diagnostic (IVD) reagents, further consolidating its leading position in the industry. Founded in 1984, SeraCare is a key partner for global in vitro diagnostic manufacturers and clinical laboratories, and became part of the LGC Group in 2018.
