CLEC2D and Familial prostate cancer: Furthermore, when the tissues were stained with LLT1 Ab (mouse anti-human CLEC2D Ab, Lifespan Biosciences, Seattle, WA) and counter stained with anti-Mouse-IgG-Dylight 594 Ab, prostate cancer tissues (Figure 5A, 5C) showed high expression of LLT1 (shown by the red/pink stain) as compared to normal prostate tissues (Figure 5B, 5D) that showed very minimal expression of LLT1 confirming the findings that were obtained in prostate cancer cell lines.
