Collagen I alpha 1 Antibody (COL-1) Summary
This Collagen I alpha 1 antibody (COL-1) was raised against full length bovine native protein (purified).
The epitope recognized by the antibody may be sensitive to routine formalin fixation and paraffin embedding.
This Collagen I alpha 1 antibody (COL-1) recognizes the native (helical) form of collagen type I using ELISA and dot-blot. It does not react with the thermally-denatured molecule, and shows no cross-reactivity with collagen types II, III, IV, V, VI, VII, IX, X and XI.

Use in WB reported in scientifc literature (PMID: 30486863). If using for WB, we recommend performing immunoblotting in non-reducing conditions. In IHC testing of acetone-fixed or unfixed frozen sections, strong staining of connective tissue fibers is seen. This antibody has been used in IHC as reported in the literature (PMID: 22019120) including IHC-Paraffin (PMID 24242003) and ICC (PMID 27769912). Use in Flow Cytometry reported by customer review.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Reported reactivity in deer. Mouse reactivity reported in scientific literature (PMID: 25287675). Goat reactivity reported by customer review. Please note that this antibody is reactive to Mouse and derived from the same host, Mouse. Mouse-On-Mouse blocking reagent may be needed for IHC and ICC experiments to reduce high background signal. You can find these reagents under catalog numbers PK-2200-NB and MP-2400-NB. Please contact Technical Support if you have any questions.

Collagen is an extracellular matrix protein that serves as a scaffold defining the shape and mechanical properties of many tissues and organs including skin, tendon, artery walls, fibrocartilage, bone and teeth. Collagens are highly conserved and are characterized by an uninterrupted "Glycine X Y" triplet repeat that is a necessary part of the triple helical structure. The extensive family of collagens is composed of several chain types, including fibril-forming interstitial collagens (types I, II, III and V) and basement membrane collagens (type IV), each type containing multiple isoforms. Collagen type I (also known as collagen alpha, COL1A1, and alpha-1 type I collagen) is the largest component of fibrillar collagen found in cartilage and connective tissues. It is synthesized by fibroblasts, osteoblasts, and odontoblasts and has a theoretical molecular weight of 138 kDa.
Type I collagen is a fibril-forming collagen found in most connective tissues and is abundant in bone, cornea, dermis and tendon tissue. Collagens are fibrous, extracellular matrix proteins with high tensile strength and are the major components of connective tissue. Several collagens play a role in cell adhesion, responsible for maintaining normal tissue architecture and function. All collagens contain a triple helix domain and frequently show lateral self-association in order to form complex connective tissues. Post-Golgi LH3 trafficking is essential for collagen homeostasis and for the development and function of multiple organs and tissues (1).
The COL1A1 gene encodes the pro-alpha1 chains of type I collagen protein, whose triple helix is comprised of two alpha1 chains and one alpha2 chain. Mutations in the encoding COL1A1 gene are associated with brittle bone disease (Osteogenesis Imperfecta), cortical hyperostosis (Caffey disease) and disorders that affect the connective tissues (Ehlers-Danlos syndrome) (2). Studies have found that HIF-1 transcription regulation of collagen prolyl hydroxylases regulates collagen deposition, promoting cancer cell alignment along collagen fibers, which enhances invasion and metastasis to lymph nodes and lung tissue by breast cancer cells (3).

FAQs for Collagen I alpha 1 Antibody (NB600-450). (Showing 1 - 5 of 5 FAQs).
We are looking for an anti-Collagen antibody for Flow Cytometry (FACS) analysis in Swine sample. Would you please provide some references if there is any available as well?
- We currently have one antibody for porcine Collagen validated in flow cytometry (catalog # NBP1-94202).
I am looking for anti collagen 1 antibody, I see your product calls it collagen I alpha 1 is there a difference?
- Collagen I alpha 1 is the most common protein for the collagen 1 protein. There are other subunits as well (such as collagen 1 alpha 2…etc.).
The predicted molecular weight says 150kDA but the band on the gel appears at 130kDA why is that?
- Differences between the predicted and observed MW can be affected by a number of factors including PTMs, relative charges and experimental factors. These cumulative effect of these differences can be quite substantial with larger molecules such as collagen I alpha 1.
How long does delivery take for your collagen 1 alpha 1 antibody?
- Our most popular collagen I alpha 1 antibody (NB600-408) is usually in stock and ships priority overnight for next business day delivery in the U.S.
What is the dilution factor for IHC for starting? Because the range of dilution factor on the datasheet is so broad, I am confused which dilution factor is suitable for starting.
- I can recommend the following dilution to start. Keep in mind that these will all vary greatly by sample type, so these are just suggestions. You may need to use more or less antibody. For catalog number NB600-450, the dilution range is 1:1000-1:2000.
