LifeSpan BioSciences (LSBio) provides high-quality antibodies, proteins, biochemicals, ELISA and assay kits to researchers worldwide. Founded in 1995, LSBio is a leading molecular pathology company with a focus on protein localization by IHC.
With a catalog of 550,000 monoclonal and polyclonal antibodies to 20,000 targets, they offer a vast library of antibodies for most species and all major research applications, such as immunoblotting, IHC, immunofluorescence, and fluorescence-activated cell sorting. Through extensive ongoing in-house testing, more than 14,000 of these antibodies have also been identified as exceptional IHC reagents, and given the IHC-plus™ brand.
Furthermore, they offer 30,000 high-quality immunoassays, including Sandwich ELISA (enzyme-linked immunosorbent assay) kits, competitive EIA (Enzyme Immunoassay) kits, as well as cell-based and DNA-binding kits.
Antibodies
LSBio offers antibodies for multiple applications, many species, and in both conjugated and unconjugated forms. Each Antibody indicates the applications for which it has been tested, such as Western Blot, ELISA, Flow Cytometry, Immunohistochemistry on frozen or formalin-fixed paraffin tissues.
IHC-plusTM antibodies
LSBio's IHC-plus™ antibodies have been tested and identified as being optimal for use in immunohistochemistry (IHC) against formalin-fixed paraffin-embedded (FFPE) human tissues under LSBio's standardized IHC-plus™ immunohistochemistry protocol.
Each antibody is tested at multiple concentrations on more than 20 normal human tissue types, and when appropriate, multiple normal brain regions and/or cancer types. In order to be selected as an IHC-plus™ brand antibody, antibodies must have a close correlation to the published literature, be high affinity, display minimal staining artifacts, and have a high signal-to-noise ratio, such that its specific staining is considerably higher than its level of nonspecific background staining.
Path-plusTM antibodies
The LSBio Path-plus™ antibodies represent the highest quality reagents available for research pathology applications. This series of reagents was selected from among thousands of antibodies that were tested in immunohistochemistry on formalin-fixed paraffin-embedded (FFPE) tissues to be the best performers. Each antibody has been tested on 21 human tissues, including specialized tissues such as cancers or brain regions, compared to up to 20 different antibodies to that target, and ranked by performance. The antibodies that showed the highest specificity and least nonspecific staining on formalin-fixed paraffin-embedded tissues are now available for your research, designated by the PathPlus™ brand.
ELISA kits
ELISA (enzyme-linked immunosorbent assay) kits are a quick, convenient, and accurate research tool for the detection and quantitation of targets of interest in cultures and samples. LSBio offers ELISA kits for the detection of hundreds of different proteins and molecules including cytokines, growth factors and receptors. These include multiple assay formats including traditional sandwich ELISA kits, competitive ELISA kits, cell-based ELISA Kits, and DNA-binding ELISA kits, as well as phospho-specific detection for many targets. Each kit is rigorously tested to ensure precision, accuracy, sensitivity, specificity, and reproducibility.
