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".
Human (tested or 100% immunogen sequence identity)
Monoclonal [C IV 22]
IHC - Paraffin (1:400)
Specificity and Use
Collagen IV antibody was raised against pepsin fragments of human collagen IV
The antibody recognizes a conformational epitope on a helical part of native collagen IV and loses its reactivity on denaturing the collagen IV protein. The antigen is stable to formalin fixation, however. Antigen distribution: Tissue sections: Basically all basement membranes except corneal epithelium. Specificity: Human: collagen IV. Other species: bovine collagen IV).
Lyophilized from PBS pH 7.2, 10mg/ml BSA, 0.01% thimerosal
0.5ml distilled water

About Collagen IV
Type IV Collagen (ColIV or Col4) is a type of collagen found primarily in the basal lamina. The collagen IV C4 domain at the C-terminus is not removed in post-translational processing, and the fibers link head-to-head, rather than in parallel. Also, collagen IV lacks the regular glycine in every third residue necessary for the tight, collagen helix. This makes the overall arrangement more sloppy with kinks. These two features cause the collagen to form in a sheet, the form of the basal lamina.
