CD CLUSTERED ANTIBODIES  

(anti-Human and others as indicated)

NOTE: 10% Discount on purchases of  3 or more any combination of CD antibodies. Please inquire for bulk or custom formulations (without preservative or carrier).

RDI Division of Fitzgerald Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (flow cytometry, 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. All products are for in vitro research use only-not for use in or on humans or animals-not for use in diagnostics.

APPLICATION  in direct Immunofluorescence techniques

Method with ficoll purified cells


Reagents and materials

- FITC-conjugated monoclonal antibodies.

- Buffer: Phosphate Buffered Saline (PBS), containing 0.2% Bovine Serum Albumine (BSA)

- PFA: Para-Formaldehyde 1%, pH 7.2,  containing 0.2% BSA

- Microtiter plates (96 wells, V bottom) or tybes.

Procedure

1 Prepare a mononuclear cell suspension with a concentratation of 1 x 10 7 cells/ml.

2 Ad 40 µl of cell suspension to microtiter wells or tubes.

3 Add 10 µl of the antibody to the microtiter wells or tubes and mix gently.

4 Incubate for 30 minutes at 2-8°C.

5 Add 150 µl buffer to the microtiter wells or 2 ml buffer to the tubes and centrifuge at 500 x g for 5 minutes.

6 Aspirate the supernatant from the cell pellet and resuspend the cells.

7 Add 200 µl buffer to the microtiter wells or 2 ml buffer to the tubes and centrifuge at 500 x g for 5 minutes.

8 Aspirate the supernatant from the cell pellet and resuspend the cells.

9 Cytoflow fluorometer analysis:

   Add 200 µl buffer to the microtiter wells and transfer this final cell suspension to appropriate testtubes, or add 200 µl                buffer to the tubes.

10 If analysis within 8 hours is not possible add at no. 9, instead of buffer, 200 µl PFA 1%.

WHOLE blood method

Due to sophisticated laser flowcytometry we are now able to distinguish populations of human lymphocytes, monocytes and granulocytes by their characteristics in different light scattering. By gating on the appropriate cell cluster (Fig.2) we can easily determine mononuclear cells, which have been immunofluorescently stained with monoclonal antibodies, and enumerate them.


Reagents and materials

- FITC-conjugated monoclonal antibodies.

- Lysing solution (NH 4Cl, pH 7.2).

- Buffer: PBS, containing 0.2 % BSA.

- PFA: Para-Formaldehyde 1%, pH 7.2, containing  0.2 % BSA.

- Tubes.


Procedure

1 Draw blood into a blood collection tube containing EDTA.

2 Deliver 100 µl (*) of well mixed whole blood to the bottom of the testtube.

3 Add 10 µl of the undiluted antibody to the bottom of the testtube, and mix gently.

4 Incubate for 30 minutes at 2-8°C or in an ice-water bath.

5 Mix the tubes and add 2 ml of lysing solution.

6 Incubate for 3-5 minutes at room temperature.

7 When lysing is completed, centrifuge the tubes at 500 x g for 5 minutes.

8 Aspirate the supernatant from the cell pellet, resuspend the cells in 1 ml buffer.

   Place the tubes in the ice-water bath.

9 Analyse the samples within 8 hours.

If analysis within 8 hours is not possible centrifuge the tubes at 500 x g. Aspirate the supernatant from the cell pellet and resuspend the cells in 1 ml PFA 1%.

Note:Use our special negative control to determine background fluorescence produced due to Fc binding capacities by mononuclear cells.The concentration and F/P ratio of our control has been adjusted to our FITC-conjugated monoclonal antibodies. * This method was developed for blood samples with a normal white count. It may be necessary to adjust the quantity of blood for samples with very high or low white counts

PRESENTATION: Each monoclonal is delivered in a sealed vial at a concentration of not less than 200µg/2ml in phosphate buffered saline containing 10mM sodium azide and 1mg/ml of bovine serum albumin. We recommend that each laboratory determine an optimum working titre for use in its particular application.

STORAGE: Purified monoclonal antibodies are generally stable for long periods at 4oC. However repeated warming to room temperature and re-cooling may result in a loss of activity and hence effective working titre. It is recommended that monoclonal antibodies are aliquotted upon receipt and then stored at -20C. After thawing they should then be used as a stock solution for up to 30 days. Dilute working solutions are best prepared on the day of use.
