ANTIBODIES  

(anti-Human and others as indicated)

RDI Division of Fitzgerald 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.


4clones available for western blotting, flow cytometry and histochemistry use

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

-see also new Goat anti-ubiquitin L1 antibody


DATA SHEET: Mouse anti-Ubiquitin monoclonal

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.

Immunogen Purified bovine erythrocyte ubiquitin


Hybridoma Myeloma P3 U1 X P1 mouse (C57BL/6xBalb/c) spleen cells


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.


The antibody can detect a ubiquitin band migrated to molecular weight of 5.5 Kd by SDS-PAGE.


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).
