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 antibody pair provided in this kit recognizes human CEA / Carcinoembryonic Antigen.
LS-F432 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human CEA / Carcinoembryonic Antigen in samples of Cell Culture Supernatants, Plasma and Serum. It is based upon a Sandwich assay principle and can be used to detect levels of CEA / Carcinoembryonic Antigen as low as 0.343 nanograms per millilter.

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.

About CEA / Carcinoembryonic Antigen
Carcinoembryonic antigen (CEA) describes a set of highly related glycoproteins involved in cell adhesion. CEA is normally produced in gastrointestinal tissue during fetal development, but the production stops before birth. Therefore CEA is usually present only at very low levels in the blood of healthy adults. However, the serum levels are raised in some types of cancer, which means that it can be used as a tumor marker in clinical tests. Serum levels can also be elevated in heavy smokers.
