LifeSpan BioSciences provides high-quality antibodies, proteins, biochemicals, ELISA and Assay kits, immunohistochemistry data and services to researchers worldwide.
LSBio has a catalog of 550,000 monoclonal and polyclonal antibodies to 20,000 targets. Antibodies are available 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.
LSBio also offers 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. LSBio also offers 45,000 native protein extracts as well as engineered recombinant proteins in the form of cell lysates or highly-purified reagents. More recently LSBio has released their growing collections of Assay Kits and BioChemicals intended to complement their other product lines for the research community.
Antibodies
We have a big collection of monoclonal and polyclonal antibodies to most target proteins. They cover all major research species, applications, and are available in multiple conjugated forms. Our IHC-plus™ antibodies are highly characterized for use in FFPE human tissue Immunohistochemistry.
ELISA & Assay Kit
Traditional Sandwich, Competitive EIA, and Direct ELISA kits provide a means to quantitatively measure thousands of targets of interest, while Cell-Based and DNA-Binding ELISA kits are ideal for in-vitro studies and transcription factor analysis.
Proteins
Proteins can be used in a wide variety of applications, such as for the development of functional assays, small-molecule screening, receptor activation in-situ, or simply as controls for a Western Blot. We offer extracted native proteins and recombinant proteins in the form of cell lysates, or purified from bacterial or mammalian expression systems. Many proteins are bio-active and certified low-endotoxin.
