Human colon carcinoma cell line SW11162.
Reacts with sialylated Lea-active pentasaccharide (sialylated lacto-N-fucopentose II). Recognizes the sialic acid-containing residue of the monosialoganglioside. Removal of the sialic acid residue with neuraminidase treatment eliminates positive reactivity with this antibody. Species cross-reactivity: Human.
Immunohistology (Formalin/paraffin): (Use Ab at 1:10-1:20 for 30 min at RT) No special pretreatment is required for staining of formalin-fixed, paraffin-embedded tissues. Positive control: Colon carcinoma.
