Specifications

  • HOST SPECIES: Rabbit
  • SPECIES REACTIVITY: Human
  • HOMOLOGY: Predicted species reactivity based on immunogen sequence: Mouse (86%); Rat: (86%)
  • IMMUNOGEN: Anti-TEM-1 antibody (4357) was raised against a peptide corresponding to 14 amino acids near the carboxy terminus of human TEM-1.
    The immunogen is located within the last 50 amino acids of TEM-1.
  • CONJUGATE: Unconjugated
  • TESTED APPLICATIONS: ELISA, IF, IHC-P, WB
  • APPLICATION NOTE: WB: 0.5-2 μg/mL; IHC-P: 2.5 μg/mL; IF: 20 μg/mL.
    Antibody validated: Western Blot in human and mouse samples; Immunohistochemistry in human samples and Immunofluorescence in human samples. All other applications and species not yet tested.
  • SPECIFICITY: At least two isoforms of TEM1 are known to exist; this antibody recognizes both isoforms.
  • POSITIVE CONTROL 1: Cat. No. 1320 - Human Colon Tissue Lysate
  • POSITIVE CONTROL 2: Cat. No. 1223 - Caco-2 Cell Lysate
  • POSITIVE CONTROL 3: Cat. No. 1219 – MCF-7 Cell Lysate
  • POSITIVE CONTROL 4: Cat. No. 1220 – SK-N-SH Cell Lysate
  • PREDICTED MOLECULAR WEIGHT: Predicted: 81kD and 46kD
    Observed: 90 kD (post-modifications: 27 O-linked glycosylations) and 46kD

Advanced Validation

  • VALIDATION:

    Independent Antibody Validation in Cell lines (Figure 2) shows similar TEM-1 expression profile in human and mouse cell lines detected by two independent anti-TEM-1 antibodies that recognize different epitopes, 4357 against C-terminus domain and 4359 against N-terminus domain.  TEM-1 proteins are detected in the most tested cell lines at different expression levels by the two independent antibodies. 

  • ISOFORMS: Human TEM-1 has 2 isoforms, including isoform 1 (757aa, 81kD) and isoform 2 (433aa, 46kD). Mouse TEM-1 has one isoform (765aa, 82kD) and rat TEM-1 also has one isoform (764aa, 82kD). 4357 can detect all isoforms of human, mouse and rat.

Background

  • TEM1 Antibody: Tumor endothelial marker (TEM) 1 was originally identified as a human embryonic fibroblast-specific antigen and was later determined to be endosialin, a single-pass transmembrane glycoprotein that has multiple extracellular domains, including three EGF-like domains, a sushi-like domain, and a C lectin-like domain. TEM proteins are significantly up-regulated during angiogenesis and neoangiogenesis that are crucial for the growth of solid tumors. While TEM1 is not required for angiogenesis during fetal development, postnatal growth or wound healing, it plays a role in tumor growth, invasion, and metastasis. Fibronectin and collagen types I and IV act as specific ligands of TEM1, leading to suggestions that these molecules may cause changes in the extracellular matrix, cell adhesion and migration during tumor invasion.
