Fluorescein isothiocyanate (Molecular Probes).

Probennahme: 1. Transfer 100 µl of anticoagulated (EDTA) blood to a 12 x 75 mm polystyrene test tube (10^6 cells). 2. Add 20 µl of CD16 FITC and mix gently with a vortex mixer. The 20 µl is a guideline only, the optimal volume should be determined by the individual laboratory. 3. The recommended negative control is a non-reactive FITC-conjugated antibody of the same isotype. 4. Incubate in the dark at room temperature at 4°C for 30 minutes or at room temperature (20-25 °C) for 15 minutes. 5. Add 1,5 ml of Lysing Solution to each sample and mix gently with a vortex mixer. Incubate for 10 minutes at room temperature in the dark. 6. Centrifuge at 1000 x g for 5 minutes. Gently aspirate the supernatant and discard it leaving approximately 50 µl of fluid. 7. Add 2 ml 0.01 mol/l PBS (It betters that it containing 2% bovine serum albumin) and resuspend the cells by using a vortex mixer. 8. Centrifuge at 1000 x g for 5 minutes. Gently aspirate the supernatant and discard it leaving approximately 50 µl of fluid. 9. Resuspend pellet in an appropriate fluid for flow cytometry, e.g. 0.3 ml PBS. The PBS should contain 1% paraformaldehyde (fixative) if samples are not analysed the same day. 10. Analyse on a flow cytometer or store at 2-8 °C in the dark until analysis. Samples can be run up to 24 hours after lysis.

Beschränkungen: Nur für Forschungszwecke einsetzbar

Handhabung

Format: Liquid

Buffer: The conjugate is provided in liquid form in buffer containing 1% bovine serum albumin (BSA) and 0,09% Sodium azide, pH 7.2.

Konservierungsmittel: Sodium azide

Vorsichtsmaßnahmen: 1. The device is not intended for clinical use including diagnosis, prognosis, and monitoring of a disease state, and it must not be used in conjunction with patient records or treatment. 2. This product contains Sodium azide (NaN3), a chemical highly toxic in pure form. At product concentrations, though not classified as hazardous, Sodium azide may react with lead and copper plumbing to form highly explosive build-ups of metal azides. Upon disposal, flush with large volumes of water to prevent metal azide build-up in plumbing. 3. As with any product derived from biological sources, proper handling procedures should be used.

Lagerung: 4 °C

Hintergrund: The CD16 molecule has been described as the low affinity Fc receptor (FcRII) for complexed IgG which may exist either as a transmembranous form or as glycosyl phosphatidylinositol form. It is expressed on NK cells, granulocytes (PMN) and macrophages. The GPI-linked form is also expressed on neutrophils. We have produced a monoclonal antibody, GRM1, against a prolymphocytic leukemia that defines an antigen present in neutrophilic granulocytes (PMN) and a lymphocyte subset with natural killer (NK) activity, which was identified as large granular lymphocytes. This monoclonal antibody recognizes FcR2 (CD16), an antigen composed of two polypeptides of 50 and 60 kDa, respectively. This GRM1 monoclonal antibody was tested against normal T and B cells, neutrophilic granulocytes, monocytes, platelets, acute and chronic leukemias, and was positive only against granulocytes (95%) and cells with NK activity. GRM1 was able to deplete NK cell activity in complement-dependent lysis. However, GRM1 did not block NK activity nor peripheral blood lymphocyte- and PMN-mediated antibody-dependent cytotoxicity in healthy individuals. GRM1 also did not block Fc receptor in an erythrocyte antibody rosette assay. The immunochemical data and cell distribution patterns lead us to conclude that GRM1 recognizes and FcR2 receptor epitope which is not involved in the receptor's function.
