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.
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".
LS-F2636 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human CD40 in samples of Breast Milk, Cell Culture Supernatants, Plasma, Saliva, Serum and Urine. It is based upon a Sandwich assay principle and can be used to detect levels of CD40 as low as 1 picograms per milliliter.
CD40, B-cell surface antigen CD40, B cell-associated molecule, B cell surface antigen CD40, CD40 antigen, CD40 type II isoform, p50, Bp50, CD40L receptor, CDW40, TNFRSF5
This kit is for the detection of natural and recombinant human CD40. No significant cross-reactivity or interference between CD40 and analogs was observed.

Due to their limited shelf life, LSBio ELISA kits are not typically stocked as finished goods. Upon receipt of an order each kit is assembled and tested to ensure that it meets specifications before shipping. Minor changes may occur to the Range, Sensitivity, and Precision. In the event of a significant change the order would be confirmed with the customer before shipping ELISA kit lot numbers reflect the date of final assembly and testing for each specific kit rather than a bulk manufactured lot. All kits are tested to confirm that they fall within their defined Inter- and Intra- assay coefficient of variation.
CD40 is a member of the TNF-receptor superfamily. The encoded protein is a receptor on antigen-presenting cells of the immune system and is essential for mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation.
