Key Applications	Immunocytochemistry Immunohistochemistry Immunohistochemistry (Paraffin)
Application Notes	Immunocytochemistry: (5 μg/ml) Immunohistochemistry: (5 μg/ml) See IHC2011-6 for prediluted and detailed paraffin protocols. Optimal working dilutions must be determined by end user. Immunohysto/cyto chemistry Protocols Ideal specimens are obtained from frozen sections from shock-frozen tissue samples. The frozen sections are dried in the air and then fixed with acetone at -20°C for 10 min. Excess acetone is allowed to evaporate at 15-25°C. Material fixed in alcohol and embedded in paraffin can also be used (2). Formaldehyde fixation will reduce or eliminate the intensity of staining depending on the conditions under which it is performed. Other fixation conditions must be first tested by the investigator. It is advantageous to block unspecific binding sites by overlaying the sections with fetal calf serum for 20-30 min at 15-25°C. Excess of fetal calf serum is removed by decanting before application of the antibody solution. Cytocentrifuge preparations of single cells or cell smears are also fixed in acetone. These preparations should, however not be dried in the air. Instead, the excess acetone is removed by briefly washing in phosphate-buffered saline (PBS). Further treatment is then as follows: • Overlay the preparation with 10-20 μl antibody solution and incubate in a humid chamber at 37°C for 1 h. • Dip the slide briefly in PBS and then wash 3 x in PBS for 3 min (using a fresh PBS bath in each case). • Wipe the margins of the preparation dry and overlay the preparation with 10-20 μl of a solution of anti-mouse Ig-FITC or anti-mouse IgG-peroxidase solution and allow to incubate for 1 h at 37°C in a humid chamber. • Wash the slide as described above. The preparation must not be allowed to dry out during any of the steps. If using an indirect immunofluorescence technique, the preparation should be overlaid with a suitable embedding medium (e.g. Moviol, Hoechst) and examined under the fluorescence microscope. If a POD-conjugate has been used as the secondary antibody, the preparation should be overlaid with a substrate solution (see below) and incubated at 15-25°C until a clearly visible redbrown color develops. A negative control (e.g. only the secondary antibody) should remain unchanged in color during this incubation period. Subsequently, the substrate is washed off with PBS and the preparation is stained, if desired, with hemalum stain for about 1 min. The hemalum solution is washed off with PBS; the preparation is embedded and examined. Substrate solutions: Aminoethyl-carbazole: Dissolve 2 mg 3-amino-9-ethylcarbazole with 1.2 ml dimethylsulfoxide and add 28.8 ml 50 mM Tris-HCI, pH 7.3, and 20 μl 3% H 2 O 2 (w/v). Prepare solution freshly each day. Diaminobenzidine: Dissolve 25 mg 3,3'-diaminobenzidine with 50 ml 50 mM Tris-HCI, pH 7.3, and add 40 μl 3% H 2 O 2 (w/v). Prepare solution freshly each day.

Biological Information
Immunogen	Purified desmin.
Clone	DE-B-5
Concentration	1 mg/mL
Host	Mouse
Specificity	The antibody reacts with desmin from human, pig, rat and taod. In tissue sections this antibody is used to stain skeletal, cardiac, visceral, and some vascular smooth muscle cells. Cell lines such as RD (ATCC CCL 136) and hamster BHK-21 are positive (Debus et al., 1983).
Isotype	IgG1
Species Reactivity	Human Pig Rat Frog
Antibody Type	Monoclonal Antibody
Entrez Gene Number	NM_001927.3
Entrez Gene Summary	This gene encodes a muscle-specific class III intermediate filament. Homopolymers of this protein form a stable intracytoplasmic filamentous network connecting myofibrils to each other and to the plasma membrane. Mutations in this gene are associated with desmin-related myopathy, a familial cardiac and skeletal myopathy (CSM), and with distal myopathies.
Gene Symbol	DES CSM2 FLJ41013 FLJ39719 CSM1 FLJ41793 FLJ12025 Desmin. CMD1I desmin
UniProt Number	P17661
UniProt Summary	FUNCTION: SwissProt: P17661 # Desmin are class-III intermediate filaments found in muscle cells. In adult striated muscle they form a fibrous network connecting myofibrils to each other and to the plasma membrane from the periphery of the Z-line structures. SIZE: 470 amino acids; 53536 Da SUBUNIT: Homopolymer. SUBCELLULAR LOCATION: Cytoplasm. DISEASE: SwissProt: P17661 # Defects in DES are the cause of desmin-related cardio- skeletal myopathy (CSM) [MIM:601419]; also known as desmin-related myopathy (DRM). CSM is characterized by skeletal muscle weakness associated with cardiac conduction blocks, arrhythmias, restrictive heart failure, and by intracytoplasmic accumulation of desmin-reactive deposits in cardiac and skeletal muscle cells. A desmin-related myopathy can have a distal onset, it is then known as hereditary distal myopathy (HDM). & Defects in DES are the cause of dilated cardiomyopathy 1I (CMD1I) [MIM:604765]. CMD1I is an autosomal form of dilated cardiomyopathy characterized by ventricular dilatation and impaired systolic function. SIMILARITY: SwissProt: P17661 ## Belongs to the intermediate filament family.
