Description: The 6.7 monoclonal antibody reacts with human and non-human primate (rhesus or cynomologus) CD18, which is also known as beta2 integrin. CD18 is a 90-95 kDa type I transmembrane protein that heterodimerizes with the a chain of CD11a, CD11b and CD11c. The CD18/CD11a complex is also known as lymphocyte function-associated antigen-1 (LFA-1) and plays an important role in cellular adhesion and inflammatory reactions. CD18 is expressed broadly by human lymphocytes and monocytes. Peripheral blood granulocytes also express CD18, but at lower levels.

The 6.7 monoclonal antibody has been reported to induce the proliferation of resting T cells cultured with monocytes.

Applications Reported: This 6.7 antibody has been reported for use in flow cytometric analysis.

Applications Tested: This 6.7 antibody has been pre-diluted and tested by flow cytometric analysis of normal human peripheral blood cells. This may be used at 5 µL (0.5 µg) per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.

Super Bright 600 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 600 nm. We recommend using a 610/20 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome.

When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Complete Staining Buffer (Product # SB-4401) to minimize any non-specific polymer interactions. Please refer to the datasheet for Super Bright Staining Buffer for more information.

Light sensitivity: This tandem dye is sensitive to photo-induced oxidation. Please protect this vial and stained samples from light.

Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 µL of cell sample + 100 µL of IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4°C with minimal impact on brightness and FRET efficiency/compensation. Some generalizations regarding fluorophore performance after fixation can be made, but clone specific performance should be determined empirically.

Excitation: 405 nm; Emission: 600 nm; Laser: Violet Laser
