| Sialyl Lea is synthesized from type 1 blood group precursor chains and is present in individuals expressing the Lea and/or Leb blood group antigens. | | | Catalog # | C0075-31A | | Epitope | Sialic acid-containing residue of the monosialoganglioside (3). | | Applications | 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. | | Cellular Localization | Cell membrane | | Storage and Stability | May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20°C or colder. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. | | CAS Number | n/a | | Clone Type | Monoclonal | | Isotype | IgG1 | | Clone No | 5G18 | | Host | Mouse | | Source | Human | | Concentration | Not determined | | Form | Supplied as a liquid with 0.09% sodium azide. | | Purity | Culture supernatant | | Immunogen | Human colon carcinoma cell line SW11162. | | Specificity | 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 Crossreactivity: Human. | | | Important Note | This product as supplied is intended for research use only, not for use in human, therapeutic or diagnostic applications without the expressed written authorization of United States Biological. |
