COL3 Antikörper

Produktnummer ABIN5596830

Produktdetails anti-COL3 Antikörper

Target: COL3 (Collagen, Type III (COL3))

Reaktivität: Human, Rind (Kuh), Säugetier

Wirt: Kaninchen

Klonalität: Polyklonal

Konjugat: Dieser COL3 Antikörper ist unkonjugiert

Applikation: Western Blotting (WB), ELISA, Immunohistochemistry (IHC), Immunoprecipitation (IP)

Kreuzreaktivität (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 III collagens and has negligible cross-reactivity with Type I, II, IV, 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.

Aufreinigung: Collagen III Antibody 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.

Immunogen:

Immunogen: Collagen Type III from human and bovine placenta

Immunogen Type: Native Protein

Isotyp: IgG

Anmerkungen:

• 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.

• The anti-COL3 antibody ABIN5596830 tends to cause a rather ubiquitous cytoplasmic staining of all kinds of cells including epithelial cells. This cytoplasmic staining is reduced to a tolerable level at dilutions of 1:225 and less. At such dilutions, ABIN5596830 stains fibrillar structures – also detected by the two reference antibodies - at weak to moderate intensity. Based on the identical staining pattern obtained by three different collagen III antibodies, these fibrillar staining’s are likely due to a binding of the antibodies to collagen III. Collagen III staining is typically located adjacent to epithelial structures, in smooth muscles or around vessels of all sizes, and in the stroma of tumors.

• ABIN5596830 cross-reacts with some inflammatory cells in lymph nodes.

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. Ideal for investigators involved in Cell Biology, Signal Transduction and Stem Cell research.
