Article Title: The v8-10 variant isoform of CD44 is selectively expressed in the normal human colonic stem cell niche and frequently is overexpressed in colon carcinomas during tumor development

Figure Lengend Snippet: Summary of screening results on the panel of anti-CD44 rabbit genomic antibodies . Flow cytometric analyses showed that four antibodies (1681, 4077, 4081, 4083) had strong reactivity to their corresponding antigens (Figure S2). Sandwich ELISA immunoassays showed that five antibodies (4077–4081) had reactivity to antigens. IHC staining was used to screen reactivity against matched normal versus malignant colonic tissue samples. We found that: i ) Three antibodies (4076, 4077, 4083) stained both normal colonic epithelial and colon carcinoma tissues; ii ) Three antibodies (4081, 4082, 4085) strongly stained colon carcinomas, but did not stain normal colonic epithelium; iii ). One antibody (4080) stained normal colonic epithelium, but not colon carcinoma.
