Flow Cytometry - Anti-CD8 alpha antibody [C8/144B] (AB17147)

Human peripheral blood lymphocytes stained with ab17147 (red line). Human whole blood was processed using a modified protocol based on Chow et al, 2005 (PMID : 16080188). In brief, human whole blood was fixed in 4% formaldehyde (methanol-free) for 10 min at 22°C. Red blood cells were then lyzed by the addition of Triton X-100 (final concentration - 0.1%) for 15 min at 37°C. For experimentation, cells were treated with 50% methanol (-20°C) for 15 min at 4°C. Cells were then incubated with the antibody (ab17147, 1/100 dilution) for 30 min at 4°C. The secondary antibody used was Alexa Fluor^® 488 goat anti-mouse IgG (H&L) (ab150113) at 1/2000 dilution for 30 min at 4°C. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 1μg/1x10⁶ cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >30,000 total events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter. Gating strategy - peripheral blood lymphocytes.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CD8 alpha antibody [C8/144B] (AB17147)

Analysis of tumor-infiltrating lymphocytes. Immunohistochemical analysis of CD8 and CD4 (Original magnification, ×20). Typical examples of each staining are shown in both groups. Statistical analysis of each staining is shown. The number of CD8 (+) lymphocytes tends to be higher in the CS (+) group than in the CS (−) group, but the difference is not statistically significant (p = 0.052). The number of CD4 (+) lymphocytes shows no significant difference between the two groups (p = 0.28). Data represent the mean ± standard error of mean (CD4 and CD8, student's t-test).
