Specificity / Sensitivity
Desmin (D93F5) XP® Rabbit mAb, Keratin 17 (D73C7) XP® Rabbit mAb, β-Tubulin (9F3) Rabbit mAb, and Vimentin (D21H3) XP® Rabbit mAb, and B-Actin (D68) Rabbit mAb recognize endogenous levels of total respective target proteins. Pan-Keratin (C11) Mouse mAb detects endogenous levels of total keratins 4, 5, 6, 8, 10, 13, and 18. This antibody does not cross-react with other keratins.
Western blot analysis of extracts from COS-7, NIH/3T3, and PC12 cells using β-Tubulin (9F3) Rabbit mAb #2128.
Western blot analysis of extracts from A-431, HeLa, and A549 cells using Keratin 17 (D73C7) XP® Rabbit mAb #4543. As expected, A549 cells are negative for keratin 17.
Western blot analysis of extracts from various cell lines using Pan-Keratin (C11) Mouse mAb #4545.
Western blot analysis of extracts from C2C12 cells, and rat and human heart using Desmin (D93F5) XP® Rabbit mAb #5332.
Western blot analysis of extracts from various cell lines using Vimentin (D21H3) XP® Rabbit mAb #5741.
The Cytoskeletal Marker Antibody Sampler Kit provides an economical means to evaluate the presence and status of select cytoskeleton associated proteins. The kit provides enough primary antibodies to perform four western blots per primary antibody.
Source / Purification
Rabbit monoclonal antibodies are produced by immunizing animals with a synthetic peptide cooresponding to residues near the amino terminus of human β-actin protein, carboxy terminal residues of human desmin protein, residues near the carboxy terminus of human keratin 17 protein, the amino terminus of human β-tubulin protein, or residues surrounding Arg45 of human vimentin protein. Mouse monoclonal antibody is produced by immunizing animals with a cytoskeleton preparation from A-431 cells.
The cytoskeleton consists of three different types of cystosolic fibers: microtubules, microfilaments (actin) and intermediate filaments. Actin, a ubiquitous eukaryotic protein, is the major component of the cytoskeleton. At least six isoforms are known in mammals. Nonmuscle β- and γ-actin, also known as cytoplasmic actin, are predominantly expressed in nonmuscle cells, controlling cell structure and motility (1). Major types of intermediate filaments are distinguished in part by the tissue in which they are expressed, for example; cytokeratins (epithelial cells), vimentin (mesenchyme origin), and desmin (skeletal, visceral and certain vascular smooth muscle cells) (2). Keratin heterodimers composed of an acidic keratin (or type I keratin, keratins 9 to 23) and a basic keratin (or type II keratin, keratins 1 to 8) assemble to form intermediate filaments (3). Research studies have demonstrated that vimentin is present in sarcomas, but not carcinomas, and its expression is examined relative to other markers in order to distinguish between the two forms of neoplasm (4). Desmin is a myogenic marker expressed in early development that forms a network of filaments that extends across the myofibril and surrounds Z discs (5). α/β-tubulin heterodimers form the tubulin subunit that comprises the microtubule building block (6)..
