Product Information

Product Usage Information

This product is the carrier free version of product #96321. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

Formulation

Supplied in 1X PBS (10 mM Na₂HPO₄, 3 mM KCl, 2 mM KH₂PO₄, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

For standard formulation of this product see product #96321

Storage

Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

Specificity / Sensitivity

COL11A1 (E6X3Y) Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total COL11A1 protein.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Glu320 of human COL11A1 protein.

Background

The Extracellular Matrix (ECM) is a complex network of macromolecules that provides structural tissue support to cells in the basement membrane and interstitial matrix. It is composed of many molecules, including proteins, glycoproteins, proteoglycans, and polysaccharides (1,2). One of the major proteins that comprise the ECM, and the human body, is collagen. Collagens are a large family of proteins. They are trimeric molecules composed of three alpha polypeptide chains that form a triple helix structure that is characteristic of all collagens (3). The large family of collagens is divided into three subgroups: the fibrillar collagens, the non-fibril forming collagens, and the fibril-associated collagens. These subgroups differ in their structure and supramolecular assembly (3).

Collagen11A1 (COL11A1) is a minor fibrillar collagen that is not normally expressed at high levels in most normal tissues with the exception of cartilage, where it is expressed in high levels, and some other tissues/ organs, where it is expressed at a lower level (4). However, it has been reported that the expression of this molecule is correlated with advanced tumorigenic disease through meta analysis of data from multiple cancers, including ovarian, colon, breast, and lung (5). Additionally, it has also been associated with epithelial-mesenchymal transition (EMT) and metastasis (6,7). Cancer associated fibroblasts (CAFs) are typically the most abundant cell type in the stroma of many solid tumors. They are thought to contribute to ECM stiffness, which is ultimately thought to contribute to tumor growth and resistance to chemotherapeutic intervention. COL11A1 has been found to be elevated in CAFs and may contribute to chemotherapy resistance (8).
