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".
For the detection and quantification of endogenous levels of natural and/or recombinant Human IGFBP1 proteins.
LS-F24536 is a 96-well enzyme-linked immunosorbent assay (ELISA) for the Quantitative detection of Human IGFBP1 in samples of Cell Culture Supernatants, Plasma, Serum and Urine. It is based upon a Sandwich assay principle and can be used to detect levels of IGFBP1 as low as 1 picograms per milliliter.
All LSBio Custom kits have been predesigned and all necessary components, including antibodies and standards have been identified. Upon receiving a custom kit order, the kit will be assembled and quality control tested before being shipped out. Kit assembly and testing typically takes 4 to 6 weeks. In most cases the final kit is based on the Sandwich assay principle, with a few being Competitive EIA based. Specifications such as Range, Sensitivity, and Precision are defined upon completion. In the event that the custom kit cannot be successfully developed with 6 weeks of the order date, the customer will be notified and the order canceled at no cost.

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.

IGFBP1 is also known as amniotic fluid binding protein (AFBP), placental protein-12, alpha-pregnancy-associated endometrial globulin, growth hormone independent binding protein, binding protein-28, binding protein-26, and binding protein-25. The low-molecular weight insulin-like growth-factor binding protein (IGF-BP25) is synthesized by human liver, secretory endometrium and decidua, and is also present in human serum. It binds insulin-like growth factors IGF-I and IGF-II with high affinity, and is proposed to act as a paracrine regulator of cell growth. These IGF-binding proteins are expressed at different concentrations in different tissues and are thought to regulate the activity of IGF I and II. The gene is organized in four exons and spans 5.9 kb. The IBP-1 gene is a single copy gene, located on chromosome 7.
Store at 4°C for 6 months or at -20°C for one year. Avoid freeze/thaw cycles.
IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Promotes cell migration.
