  • Immunohistochemistry Services

  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

The LSBio Guarantee

LSBio stands behind the quality of its products 100%

LSBio guarantees that every product will meet the standards defined on its individual product specification sheet.  If a LifeSpan product fails to work as stated, LSBio’s technical support group will work closely with the customer to provide experienced product support.  Products that have been damaged in transit, those that don’t meet their defined specifications upon receipt and proper storage, and those for which the troubleshooting process fails will be replaced or credited.  The following are considerations for specific LSBio product lines:

Antibodies: LSBio antibodies are guaranteed to work in those applications, and cross-react with those species, listed on their individual product specification sheets.  Due to the highly specific nature of antibodies and antigens, we cannot predict or be held responsible with respect to how LSBio products will behave in our customers' systems. Researchers using LSBio products should conduct optimization studies to achieve the best result possible for their intended application.

Proteins and Peptides: LSBio proteins and peptides are guaranteed to meet the structural and purity specifications listed on their individual product specification sheets.  Due to the diversity of applications in which proteins can be used, LSBio is unable to guarantee the successful use of an LSBio protein product in specific applications.  The biological activity of a protein is dependent upon specific assay conditions and therefore LSBio can only guarantee the specified biological activity of a protein product as tested internally, and not in client applications.

Immunoassays: LSBio guarantees that our immunoassays will work for those species and sample types defined in each individual kit manual.  However, due to the valuable and often irreplaceable nature of experimental samples, it is very strongly recommended that customers first test each kit using less valuable positive control samples generated in a similar manner to the experimental samples. Due to the perishable nature of ELISA kits, orders of greater than 5 units of a single catalog number cannot be returned, and are not eligible for refund. 


Terms & Conditions

Eligibility requires that customers complete a LSBio Return Claim Form within 6 months of purchase. LSBio reserves the right to refuse the eligibility of any customer to this guarantee at its discretion and does not offer returns or refunds beyond 6 months of product purchase date. When issued, refunds are limited to the list price of the Returned Product and replacements are limited to products of comparable list price to the failed Product.
