  • Immunofluorescence staining of MCF-7 cells with CSB-PA857459EA01HU at 1:133, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).

Gene References into Functions
  1. A33 shows similar sensitivity to but is more specific than CDX2 as an immunomarker of colorectal carcinoma PMID: 28226180
  2. A33 expression is directly correlated to colorectal tumor differentiation. PMID: 27272411
  3. Data indicate that EpCAM- and A33-Exos were released from the apical and basolateral surfaces, respectively. PMID: 23230278
  4. Data indicate positive staining was observed for both A33 expression and KRN330 binding from patients biopsied on Day 8, 9 or 14 following initial dosing of 3 mg/kg. PMID: 23294608
  5. The A33-dependent incorporation of B5 into extracellular enveloped vaccinia virions is mediated through an interaction between their lumenal domains. PMID: 22623777
  6. Increased interaction between vaccinia virus proteins A33 and B5 is detrimental to infectious extracellular enveloped virion production. PMID: 22623782
  7. cloning, chromosomal localizations, exon-intron structures and transcription start sites - target gene for the intestine-specific homeobox transcription factor, CDX1. PMID: 12114523
  8. Regulation of A33 antigen expression by GKLF. PMID: 12853980
  9. This work has demonstrated that the antigen is both highly immobile and extremely persistent-retaining its surface localization for a turnover halflife of greater than 2 days. PMID: 18236042
