Anti-TEM7 (Tumor Endothelial Marker 7, Plexin Domain Containing 1, Plexin Domain-containing Protein

Recently, using SAGE (Serial Analysis of Gene Expression) technology, St. Croix et al, have identified 46 genes, whose expression is specifically elevated in tumor-associated endothelium. Nine of these genes were prominently expressed only in tumor endothelial cells (EC), but were absent or barely detectable in normal ECs, and named as Tumor Endothelial Markers (TEMs, TEM 1-9). TEM7 (Tumor endothelial marker 7) transcripts are specifically expressed in the endothelium of colorectal cancer, primary cancers of lung, pancreas, breast, and brain. TEM7 is expressed specifically in endothelium of these cancers, whether primary or metastasis. The other six members of this family (TEM1, 3, 4, 5, 8, and 9) also show similar expression pattern in lung and brain tumors, and liver metastasis. Since most of the genes expressed differentially in tumor endothelium are also expressed during angiogenesis, these newly discovered genes might provide important resources for basic and clinical studies of human angiogenesis. Applications: Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Positive Control: HCT-116 , Storage and Stability:, May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20°C. Aliquots are stable for at least 3 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.
