Mouse anti CD45

The CD45 molecule is typically expressed at high levels on all hematopoietic cells. CD45 is a major component of the glycocalix of these cells and can be expressed in different isoforms. Antibody VIT200 recognizes a pan CD45 epitope, which is expressed on all hematopoietic cells. The VIT200 antibody permits the identification and enumeration of Human leukocytes using flow cytometry. _x000D_ Results must be interpreted by a certified professional before final interpretation. Analyses performed with this antibody should be paralleled by positive and negative controls. If unexpected results are obtained which cannot be attributed to differences in laboratory procedures, please contact us.

GM-4061 can be applied in immunohistochemistry on frozen and parrafin embedded tissues and in flow cytometry._x000D_ _x000D_ Direct Immunofluorescence (Staining Procedure) Nordic-MUbio fluorochrome labeled antibodies are designed for use with either whole blood or isolated mononuclear cell (MNC) preparations. Proposed staining procedure for whole blood in short: - For each sample add 50 µL of EDTA anti-coagulated blood to a 3-5 mL tube - Add 20 µL of the appropriate Nordic-MUbio monoclonal antibody conjµgate - Incubate the tube for 15 minutes at 4°C or at room temperature in the dark - Add 100 µL NM-LYSE (Cat.No. GAS-003) to each tube and incubate for 10 minutes at room temperature - Add 3-4 mL of destilled water and vortex, incubate for 5-10 minutes at room temperature - Centrifµge tube for 5 minutes at 300 g - Aspirate supernatant and resuspend pellet in 0.3 mL of sheath fluid - Analyze immediately or store samples at 2-8° C in the dark and analyze within 24 hours For “No-Wash” protocol please refer to www.nordicmubio.com Proposed staining procedure for MNC in short: - Carefully add 20 µL antibody conjµgate and 50-100 µL MNC to the bottom of a tube - Vortex at low speed for 1-2 seconds - Incubate for 15-30 minutes at 2-8°C or at room temperature - Centrifµge tubes for 5 minutes at 300 g - Remove supernatant, resuspend cells in 2-5 mL of phosphate buffered saline (PBS) and centrifµge cells again for 5 minutes at 300 g - Remove supernatant and resuspend cells in sheath fluid for immediate analysis or resuspend cells in 0.5 mL 1 % formaldehyde and store them at 2-8°C in the dark. Analyze fixed cells within 24 hours Indirect Immunofluorescence (Staining Procedure) - Mix 20 µL Nordic-MUbio purified antibody with 50 µL whole blood or MNC suspension - Incubate for 15 minutes at 2-8°C - Wash cells with phosphate buffered saline (PBS) - Add to cell pellet 20 µL of affinity purified, fluorochrome labeled F(ab’)2 anti mouse Ig antibodies - Incubate for 15 minutes at 2-8°C - Wash cells with phosphate buffered saline (PBS) or proceed as described for direct staining

For professional users only. This reagent contains sodium azide. To avoid the development of hazardous conditions, reagents containing azide should be diluted in running water prior to be discarded. Similar to the work with other biological products, proper handling procedures are recommended.

Nordic-MUbio monoclonal antibody reagents contain optimal concentrations of affinity-purified antibody; For stability reasons this monoclonal antibody solution contains sodium azide. These reagents should be stored at 2-8°C (DO NOT FREEZE!) and protected from prolonged exposure to light. If a slight precipitation occurs upon storage, this should be removed by centrifugation; It will not affect the performance or the concentration of the product Stability of the reagent: Please refer to the expiry date printed onto the vial. The use of the reagent after the expiration date is not recommended.
