  • IHC image of CSB-MA299720 diluted at 1:100 and staining in paraffin-embedded human cervical cancer performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-mouse IgG polymer labeled by HRP and visualized using 0.05% DAB.

Description

The KRT13 monoclonal antibody is produced using the hybridoma technology that involves multiple steps. It starts with the immunization of mice with the synthesized peptide derived from human KRT13. B cells are isolated from the spleen of the immunized mice and fused with myeloma cells to create hybridomas. These hybridomas are then screened to select the ones that produce antibodies specific to KRT13. Once selected, the hybridomas are cultured in the mouse abdominal cavity and the KRT13 monoclonal antibodies are purified from mouse ascites by affinity chromatography using a specific immunogen. The purified KRT13 monoclonal antibody is highly specific, reacting exclusively with human KRT13 protein in ELISA and IHC applications.

KRT13 is specifically expressed in stratified squamous epithelia, including the oral mucosa, esophagus, and female genital tract. KRT13 is involved in the formation of filaments that provide mechanical stability to epithelial cells, help to maintain the structural integrity of tissues and provide a barrier against physical and chemical stress. It also plays a role in cell signaling and the regulation of gene expression.

Target Background

Gene References into Functions
  1. Oral white sponge nevus may manifest variable clinical features. The novel mutation found in the KRT13 gene is believed to add evidence for a mutational hotspot in the mucosal keratins PMID: 29476668
  2. this study reports that KRT13 plays a directive role in prostate cancer bone, brain, and soft tissue metastases PMID: 27835867
  3. Keratin 13 gene is epigenetically suppressed during TGFB1-induced epithelial-mesenchymal transition in a human keratinocyte cell line. PMID: 29326042
  4. Four rare missense variants were identified (ACTBL2 rs73757391 (5q11.2), BTD rs200337373 (3p25.1), KRT13 rs150321809 (17q21.2) and MC2R rs104894658 (18p11.21)), but only MC2R rs104894668 had a large effect size (OR = 9.66). PMID: 27378695
  5. KRT13 expression is associated with poor prognosis at multiple stages of disease progression PMID: 27711225
  6. Loss of CK13 expression is associated with invasive oral squamous cell carcinoma. PMID: 26225699
  7. Low KRT13 mRNA expression is associated with oral squamous cell carcinoma. PMID: 25735388
  8. Decreased KRT13 was associated with Esophageal Squamous Cell Carcinoma. PMID: 25851906
  9. Our data provide mechanistic insights into the epigenetic silencing of KRT13 genes in OSCC cells and might be useful for the development of diagnostic markers and novel therapeutic approaches against OSCCs. PMID: 25527207
  10. keratin14 expression can be used to detect early epithelial dysplasia, and that keratin13 and keratin17 expression are useful for detecting neoplastic changes PMID: 24471966
  11. Immunoexpression of CK13 and CK17 in light green-stained superficial cells was associated with more severe morphological atypia in tongue squamous cell carcinoma PMID: 24247036
  12. Fluorescent keratin 13 integrates into the endogenous keratin cytoskeleton in human vulva carcinoma-derived A431 cells, thereby serving as a reliable marker of keratin dynamics. PMID: 23757496
  13. Loss of K13 in oral carcinoma in situ is partly due to its gene repression, but may also be due to some unknown post-translational events. PMID: 22301701
  14. Keratin 13 is a more specific marker of conjunctival epithelium than keratin 19. PMID: 21738394
  15. CK13 expression is elevated in KB cells treated with all-trans retinoic acid or arsenic trioxide. PMID: 19489262
  16. exhibits a regular expression pattern in luminal epithelial cells of secretory phase human endometrium PMID: 11906920
  17. Metaplastic squamous cells differentiate with a decrease of CK18 and an increase of CK13 expression. PMID: 16836912
  18. CK13 positive staining occurs in cervical squamous tumors and in mucinous cervical type adenocarcinomas, while there was no positive staining in non-neoplastic cervical glandular elements PMID: 16949723
  19. The different ligand regulations of KRT13 are due to ligand-differential recruitment of ER and coactivators. PMID: 18951949
