    Réactivité croisée (Details)
    Typically negligible cross-reactivity against other types of collagens was detected by ELISA against purified standards. Some class-specific anti-collagens may be specific for three-dimensional epitopes which may result in diminished reactivity with denatured collagen or formalin-fixed, paraffin embedded tissues. This antibody reacts with most mammalian Type IV collagens and has negligible cross-reactivity with Type I, II, III, V or VI collagens. Non-specific cross-reaction of anti-collagen antibodies with other human serum proteins or non-collagen extracellular matrix proteins is negligible.
    Purification
    Anti-Collagen Type IV has been prepared by immunoaffinity chromatography using immobilized antigens followed by extensive cross-adsorption against other collagens, human serum proteins and non-collagen extracellular matrix proteins to remove any unwanted specificities.

    Quelle est la fonction du collagène 4 ? Le collagène de type 4 est le principal composant structurel des membranes basales glomérulaires, formant un maillage en " fil de poulet " avec les laminines, les protéoglycanes et l'entactine/nidogène. (Uniprot). La protéine collagène 4 est constituée d'un domaine 7S amino-terminal, d'un domaine collagène formant une triple hélice et d'un domaine non collagène carboxy-terminal. Elle fonctionne comme une partie d'un hétérotrimère et interagit avec d'autres composants de la matrice extracellulaire tels que les perlecans, les protéoglycanes et les laminines. (NCBI)

    Notes
    • For antibody comparison an antibody test TMA was used that contained 80 normal tissues from 21 different organs and 95 neoplastic tissues from 18 different tumor types. Despite some cytoplasmic and stromal background ABIN5596819 identified identical structures as the reference antibody MSVA-704R. An additional occasional staining of nuclei which was only seen by ABIN5596819 must be considered a cross-reactivity.

    • According to the rather ubiquitous nature of collagen IV expression, orthogonal validation is not optimally suited for the validation of collagen I antibodies. In agreement with RNA screening studies, including the Human Protein Atlas (HPA) RNA-seq tissue dataset, the FANTOM5 project, and the Genotype-Tissue Expression (GTEx) project (all summarized in https://www.proteinatlas.org/ENSG00000134871-COL4A2/tissue), collagen IV staining by ABIN5596819 was particularly high in the placenta, colon, smooth muscle, and the lung. These are among the tissues with the highest recorded RNA expression.

    Background: Rockland produces highly active antibodies and conjugates to collagens. Collagens are highly conserved throughout evolution and are characterized by an uninterrupted ''Glycine-X-Y'' triplet repeat that is a necessary part of the triple helical structure. For these reasons, it is often extremely difficult to generate antibodies with specificities to collagens. The development of 'type' specific antibodies is dependent on NON-DENATURED three-dimensional epitopes. Rockland extensively purifies collagens for immunization from human and bovine placenta and cartilage by limited pepsin digestion and selective salt precipitation. This preparation results in a native conformation of the protein. Antibodies are isolated from rabbit antiserum and are extensively cross-adsorbed by immunoaffinity purification to produce 'type' specific antibodies. Greatly diminished reactivity and selectivity of these antibodies will result if denaturing and reducing conditions are used for SDS-PAGE and immunoblotting.
