Applications Description:
Staining Procedure for Surface CD3:
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 ?l of EDTA anti-coagulated blood to a 3-5 ml tube
- Add 20 ?l of the appropriate Nordic-MUbio monoclonal antibody conjugate
- Incubate the tube for 15 minutes at 4°C or at room temperature in the dark
- Add 100 ?l Nordic-MUbio-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
- Centrifuge 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 ?l antibody conjugate and 50-100 ?l 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
- Centrifuge tubes for 5 minutes at 300 g
- Remove supernatant, resuspend cells in 2-5 ml of phosphate buffered saline (PBS) and centrifuge 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 ?l Nordic-MUbio purified antibody with 50 ?l 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 ?l 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

Staining Procedure for Cytoplasmatic CD3: Permeabilization and Staining Procedure
- In combination with our Permeabilization Kit FIX&PERM? (Cat. No. GAS-002) intracellular CD3 can be easily stained in cell suspensions.
- For each sample to be analyzed add 50 ?l of whole blood, bone marrow or mononuclear cell suspension in a 5ml tube
- Add 100 ?l of Reagent A (Fixation Medium, stored and used at room temperature)
- Incubate for 15 minutes at room temperature
- Add 5ml phosphate buffered saline and centrifuge cells for 5 minutes at 300 g
- Remove supernatant and add to cell pellet 100 ?l Reagent B (Permeabilization Medium) and 20 ?l of the CD3 monoclonal antibody conjugate
- Vortex at low speed for 1-2 seconds
- Incubate for 15 minutes at room temperature
- Wash cells with phosphate buffered saline as described above
- Remove supernatant and resuspend cells in sheath fluid for immediate analysis or resuspend cells in 0.5 ml 1.0 % formaldehyde and store them at 2- 8°C in the dark.
- Analyze fixed cells within 24 hours.
Background:
UCHT1 is directed against human CD3 ? the multichain complex associated with the T-cell receptor. Precursor T-cells are surface CD3 negative but positive for cytoplasmic CD3. All mature T-cells are both cytoplasmic and surface CD3 positive.

The UCHT1 antibody permits the identification and enumeration of normal and leukemic human blood and bone marrow cells using flow cytometry.

Results must be put within the context of other diagnostic tests as well as the clinical history of the patient 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.
Caution:
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.
Formulation:

Specificity:
The CD3 mAb (clone UCHT1) recognizes cytoplasmic CD3 epsilon in precursor T-cells and cytoplasmic and surface CD3 epsilon in mature T-lymphocytes.

The sensitivity of UCHT1 mAb is determined by staining well-defined blood samples from representative donors with serial-fold mAb dilutions to obtain a titration curve that allows relating the mAb concentration to the percentage of stained cells and geometric MFI (mean fluorescence intensity).The sensitivity of UCHT1 mAb is determined by staining well-defined blood samples from representative donors with serial-fold mAb dilutions to obtain a titration curve that allows relating the mAb concentration to the percentage of stained cells and geometric MFI (mean fluorescence intensity).In practice, 50 ?l of leukocytes containing 107 cells/ml are stained with 20 ?l mAb of various dilutions to obtain a titration curve and to identify the saturation point and detection threshold. The final concentration of the product is then adjusted to be at least 3-fold above the detection threshold. In addition and to control lot-to-lot variation, the given lot is compared and adjusted to fluorescence standards with defined intensity
