Application FOR AN INDIRECT IMMUNOFLUORESCENCE TECHNIQUE



Reagents

- FITC-conjugated goat anti-mouse immunoglobulin antiserum (M1204).

   Remove aggregates by centrifugation at 1000 x g for 10 minutes.

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

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

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

Procedure

1   Fixate the cells with PFA 1% and wash them with buffer.

2   Prepare a mononuclear cell suspension with a concentration of 1 x 10 7 cells/ml in buffer.

3   Add 45 µl of cell suspension to the microtiter wells or tubes.

4   Add 5 µl monoclonal antibody to the microtiter wells or tubes and mix gently.

5   Incubate for 30 minutes at 2-8 C.

6   Add 100 µl buffer to the microtiter wells or 2 ml buffer to the tubes and centrifuge at 500 x g for 5 minutes.

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

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

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

10 Add 50 µl FITC-conjugated goat anti-mouse immunoglobulin serum, solid phase adsorbed with human immunoglobulins,       diluted 1:80.

11  Incubate for 30 minutes at 2-8 C.

12  Repeat step 6-9.

13 Add 200 µl buffer.

14 The number of positive cells can be determined by flowcytometry analysis or by means of fluorescence microscopy.

 

NOTE: Care should be taken when drawing blood to avoid activation of platelets.
Platelets activation markers are weakly expressed on platelets prepared from directly fixed normal whole blood.

The expression is maximal on thrombin (1 U/ml) stimulated washed platelets.

FOR IN VITRO RESEARCH USE ONLY


Mouse ANTI- HUMAN CD 42b ANTIGEN

PRODUCT CODE : RDI-CBL 166     $375.00/vial

Also available: FITC labeled cat#RDI-CBL166FT    $375.00/100 Test

                           PE labeled #RDI-CBL166PE        $500.00/100 Test
CLONE: AK2

ISOTYPE: IgG1

Immunizing Antigen: human platelet glycoproteins

Fusion Partner: NS1 myeloma cell line

SOURCE: Mouse ascitic fluid

PURIFICATION METHOD: Protein A affinity chromatography

SPECIFICITY: The antibody is directed against the CD42b antigen, platelet glycoprotein gp1bA, that serves as a receptor for Von Willebrand factor (vWF) and as a high affinity thrombin receptor. AK2 immunblots a band of 130kDa on SDS gels of platelet lysates and gives surface immunofluorescence with fixed or unfixed platelets. The antigen is absent in very low levels on platelets with the Bernard-Soulier syndrome..


APPLICATIONS: * Immunofluorescence studies of platelets, reacts with gp1ba molecule.

                              * Studies with platelets and magakaryocytes in frozen sections by immunohistochemistry.

                              * Functional studies involving von Willebrands adhesion receptor.

                                 -this antibody blocks vWf binding to washed platelets.

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 -200C. After thawing they should then be used as a stock solution for up to 60 days. Dilute working solutions are best prepared on the day of use.

CLONE: MM2/174

ISOTYPE: IgG1

SOURCE: Tissue culture supernatent.

PURIFICATION METHOD: Protein A affinity chromatography.

SPECIFICITY: MM2/174 immunoblots a band of 130kD on SDS gels of platelet lysates and gives surface immunofluorescence with fixed or unfixed platelets.

APPLICATIONS:

* Immunofluorescence studies of platelets, reacts with gp1b molecule.

* Studies with platelets and megakaryocytes in frozen sections by immunohistochemistry.

* Functional studies involving von Willebrands factor binding to gp1b.

Formalin fixed decalcified sections of bone marrow. Magakarocytes and platelets are labeled without pretreatment and with pretreatment using protease type XXIV (0.5mg/ml) High temp antigen retrieval citrate buffer pH6.0 may also be required

Species: mouse IgG1

Purification: purified from tissue culture supernatant by Protein G affinity chromatography

CLONE: HIP1

Workshop: IV, #P40

Activity: Reacts with a 135kd two chain membrane glycoprotein, GpIb, that forms a non covalent complex with GPIX (CD42a) found on platelets and magakaryocytes.

The GPIb/IX complex serves as the vWF surface receptor involved in the adhesion of platelets to the subendothelium of damaged vascular walls.

Application: -Indirect fluorescence

                     -adhesion (with azide free material)

                     -titers must be determined for each application|
