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.

Collagen Type III from human and bovine placenta


Purified by antigen-affinity chromatography.
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.




For laboratory use only. Not for any clinical, therapeutic, or diagnostic use in humans or animals. Not for animal or human consumption.

Cellular Localization

Extracellular matrix


These antibodies are well suited to detect extracellular matrix proteins in normal as well as disease state tissues. Disruption of tissue organization is the hallmark of neoplasia. Malignant lesions can be distinguished from benign by examining the breakdown of basement membranes and loss of 3-dimensional architecture. Malignant cells are presumed to use matrix metalloproteases to degrade barriers created by the extracellular matrix, which then allows metastasis to occur. Collagenases, stomelysins and gelatinases can collectively degrade all of the various components of the extracellular matrix, including fibrillar and non-fibrillar collagens and basement membrane glycoproteins.

Western Blot of Rabbit Anti-Collagen III Antibody (GTX27778) Load: 100 ng Human Collagen III. Primary antibody: Collagen III Antibody at 1:1000 o/n at 4°C. Secondary antibody: DyLight™ 649 Goat anti-rabbit at 1:20,000 for 30 min at RT Block for 30 min at RT. Predicted/Observed size: 138 kDa, 138 kDa.


GTX27778 IHC-P Image

GeneTex anti collagen III antibody (GTX27778, 45 min RT) showed strong staining in FFPE sections of human skin(left, dermis) with moderate to strong red staining and testis (right) where strong staining was observed within connective tissue between seminiferous tubules. The antibody showed strong extracellular staining within connective tissues across many organs with minimal background staining. Slides were steamed in 0.01 M sodium citrate buffer, pH 6.0 at 99-100°C - 20 minutes for antigen retrieval.
