  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, 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.


Mab to E-Cadherin   (Uvomorulin; L-CAM)

cat#RDI-PRO10028   $438.00

Clone                     5H9

Category                Mouse monoclonal

Form/Purification    purified IgG from culture supernatant

Ig Class                  IgG1

Immunogen             Human uvomorulin

Clinical Application/Specificity  Mab 5H9 specifically reacts with the 120 and 80 kDa ARC-1 protein in western blotting. In epithelia, E-cadherin is involved in the development and maintenance of cell layers during embryogenesis and in the adult tissue. Clustering of E-cadherin seems to occur via µ, ß and g catenins which link E-cadherin to cytoskeletal actin. Loss of E-cadherin expression seems to be correlated with the transformation state of carcinoma cells and with their metastatic potential.

INDIREKT IMMUNOPEROXIDASE STAINING ON FORMALIN-FIXED PARAFFIN- EMBEDDED TISSUE

- MICROWAVE TREATMENT -

1. Fix paraffin sections onto silanated oder polylysin-coated slides.

2. Dry overnight at 58°C.

3. Deparaffinize: dewax in xylol for 3 x 3 min; rehydrate in decreasing grades of ethanol: absolute, 96%, 70%, 50%, and dest. water for 3 min ea.

4. Microwave treatment incubate in plastic cuvette containing cold 10 mM Na-citrate buffer (pH 6.0) 5 x 5 min at 600

Watt in a microwave oven; let cool down after complete treatment to room temperature (15 min).

5. From this step onward it is essential that the sections do not dry out.

6. Rinse in dest. water and 2 x 5 min in PBS.

7. Optional: Block endogenous peroxidase with 0.6% H2O2/40% methanol-PBS for 30 min.

8. Rinse in PBS for 2 x 5 min.

9. Cover sections with 10 % heat-inactivated horse serum in PBS for 1 h (or alternatively with 5 % normal serum of the same species as the secondary antibody); depending on background staining, this step can be omitted or the serum concentration can be increased. Decant excess serum after incubation.1)

10. Incubation with optimal dilution of primary antibody (optimal dilution should be tested individually in each laboratory; start with a dilution of 1:10).

11. Rinse in PBS for 3 x 5 min.

12. Detection system: ABC method (Vector Laboratories); follow kit instructions; Counterstain with methyl green or hematoxylin

13. Dehydrate in increasing grades of ethanol, clear with xylol and mount with mounting medium

INDIRECT IMMUNOPEROXIDASE STAINING ON FROZEN SECTIONS

1. Fix sections on clean glass slides

2. Fixation in cold acetone or acetone/methanol for 5-10 min.

3. Let dry at RT

4. Rinse for 2 x 5 min in PBS

5. Optional: Block endogenous peroxidase with 0.6% H2O2/40% methanol-PBS for 30 min.

6. Rinse in PBS for 2 x 5 min.

7. Follow steps 10 -14 as given above

1) To reduce background, 2% skim milk powder may be added to the horse serum and all following incubations.
