ANTIBODIES  

(anti-Human and others as indicated)

RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, histochemistry, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Update January 13, 1998, :Note clones  1B2 & 2C5 (clone 2C5 also suitable for paraffin sections/histochemistry)

-see also new Goat anti-ubiquitin L1 antibody

Catalog Number:  RDI-ALS24509    $344.00/100ul

Clone: Ubi-1

Quantity: 100ul

Description: Ubiquitin is a highly conserved globular 76 amino acid protein of about 8.5 kDa molecular weight. It has a important role in the targeting of proteins for proteolytic degradation. Proteins to be degraded are covalantly coupled to the C-terminus of ubiquitin by means of ubiquitin ligases. The ubiquitin itself is frequently also ubiquitinated, producing a polyubiquitin chain. The polyubquitinated complex is then recognized by a complex of degradative enzymes which together form the proteosome. Interestingly, ubiquitin also becomes covalently bonded to many types of pathological inclusions seen in serious human disease states which appear to be resistant to normal degradation, so that ubiquitin antibodies are very useful for studies of these inclusions. For example the neurofibrillary tangles and paired helical filaments diagnostic of Alzheimer's disease, the Lewy bodies seen in Parkinson's disease, and Pick bodies found in Pick's disease are all heavily ubiquitinated and can all be readily visualized with ubiquitin antibodies of appropriate specificity.

Host Species: Mouse

Specificity: Ubi-1 was raised against purified ubiquitin conjugated with glutaraldehyde to keyhole limpet hemocyanin. The clone was initially screened on ELISA of the immunogen, and subsequently tested on sections of Alzheimer brain. Ubi-1 was one of several clones which stained neurofibrillary tangles in frozen sectioned material strongly and specifically. Subsequent studies indicated that MCA-Ubi-1 is relatively insensitive to formalin fixation and so can be used on mildly fixed histological sections of human brain for studies of Alzheimer's disease. The antibody also works on paraffin embedded material. Ubi-1 also recognizes other ubiquitinated inclusion bodies such as the Lewy bodies of Parkinson's disease and the Pick bodies in Pick's disease in formalin fixed tissues. Ubi-1 will recognize human, bovine, chicken, Drosophila, and C. elegans in ELISA. Ubi-1 also works on Western blots and can be used to study ubiquitinated proteins. It has also been successfully used in competitive ELISA.

Applications: Ubi-1 is excellent for the detection of ubiquitinated inclusions seen in human neurodegenerative diseases such as the neurofibrillary tangles of Alzheimer's disease. We recommend a starting dilution of 1:1,000 for this purpose, using ABC or other enzymatic amplification procedures. For immunofluorescence, use Ubi-1 diluted 1:500. For western blots use Ubi-1 diluted 1:1,000.

Format: Sterile cell culture fluid plus sodium azide. Ubi-1 is a mouse IgG1 with a kappa light chain. Supplied at a concentration of 1mg/ml.

Storage: Maintain at +2-8°C for 3 months or at -20°C for longer periods. Stable for 1 year. Avoid repeated freeze-thaw cycles.

Background: Ubiquitin protein conjugates associated with filamentous inclusions or in dot like strcutures (lyosome-releated organelles) are characteristic of the major human idiopathic neurodegenerative diseases. Dot-like strcutures are aslo a feature of the transmissable neurodegenerative diseases. This antibody detects neurofibrillary TANGLES in Alzheimer's disease, Lewy bodies in Lewy Body disease, Rosenthal fibres in astrocytomas, Mallory bodies in Alcoholic Liver Disease. Also detects dot-like structures in the white matter of normal aging brain.

Isotype IgG1

Specificity: The antibodies react with human erythrocyte ubiquitin and bovine erythrocyte ubiquitin. These antibodies (1B3 and 2C5) recognize different epitope sites each other.

Presentation:Purified from ascites fluid by ammonium sulfate precipitation and affinity chromatography on protein A sepharose. Sodium azide (0.1%) has been added as preservative.

Western immunoblotting was performed as follows.

3 ug of ubiquitin (From bovine red blood cell-) or 20ul of WIL 2 cell extracts (10(8) cells were suspended with 5 ml of SDS PAGE sample buffer and sonicated 30 sec) were first applied to a 10% polyacrylamide gel and subjected to electrophoresis according to the method of Laemmli, except for substituting the Glysinc cathode buffer with the Tricine cathode buffer (0.1M Tricine; no correction of the pH, which is around 8.25). After electrophoresis, the protein bands were transferred onto nitrocellulose paper using a Bio-Rad transblotting unit of 25 mM Tris, 192 mM glycine, 20% methanol. The nitrocellulose paper was incubated 2 h with 0.2% skim milk in PBS at room temperature. The paper was then incubated with 1ug/ml of anti ubiquitin antibodies (clone 1B3 or -2C5) in 0.2% skim milk in PBS for 2h at room temperature followed by three 5-min washes in PBS. The paper was then incubated with peroxidase conjugated rabbit anti-mouse Ig 1:125 dilution in 1% BSA in PBS) for 45 min at room temperature. After another three 5-min washes in PBS, the paper was developed with a freshly prepared solution of 3,3'-diaminobenzidine tetrahydrochloride (25 ug/ml in PBS,0.015% hydrogen peroxide).
