p63 is a homolog of the tumor suppressor p53. It is identified in basal cells in the epithelial layers of a variety of tissues, including epidermis, cervix, urothelium, breast and prostate. p63 was detected in nuclei of the basal epithelium in normal prostate glands; however, it was not expressed in malignant tumors of the prostate. As a result, p63 has been reported as a useful marker for differentiating benign from malignant lesions in the prostate, particularly when used in combination with markers of high molecular weight cytokeratins and the prostate-specific marker AMACR (P504S). p63 has also been shown to be a sensitive marker for lung squamous cell carcinomas (SqCC), with a sensitivity of ~90%. Specificity for lung SqCC, vs. lung adenocarcinoma (LADC), is approximately 80%. In breast tissue, p63 has been identified in myoepithelial cells of normal ducts.

CD34 is a surface glycophosphoprotein expressed on developmentally early lymphohematopoietic stem and progenitor cells with a molecular weight of about 105-120 kD. It is selectively expressed on the majority of hematopoietic stem/progenitor cells, bone marrow stromal cells, capillary endothelial cells, embryonic fibroblasts, and some nerve tissue. CD34 is a commonly used marker for identifying human hematopoietic stem/progenitor cells and mediates cell adhesion and lymphocyte homing by binding L-selectin and E-selectin ligands. CD34 is also one of the best negative selection markers for characterizing and/or isolating human MSCs from bone marrow and other sources. Along with other positive selection markers (such as CD29, CD44, CD90, CD105 and CD166), negative selection markers (such as CD34 and CD45) are used for MSC identification.

LyP-1 recognizes lymphatics and tumor cells in certain tumors, but not lymphatics in normal tissues. Screening on breast carcinoma xenografts shows positive to cyclic 9-amino-acid peptide, LyP-1. The LyP-1 also recognizes an osteosarcoma xenograft, and spontaneous prostate and breast cancers in transgenic mice. LyP-1 peptide is detected in tumor structures that are positive for several lymphatic endothelial markers and negative for blood vessel markers. LyP-1 accumulates in the nuclei of the putative lymphatic cells, and in the nuclei of tumor cells.

Gastrin-releasing peptide, a 27-amino acid peptide isolated from the gut, stimulates the release of Gastrin, and shares a common C-terminal decapeptide homology with bombesin. Gastrin-releasing peptide is an important growth-modulating factor in developing lung epithelium. It is used as a tumor marker in the diagnosis of small-cell lung carcinoma, since it is known to be produced by these cancer cells.

SOD2(superoxide dismutase 2, mitochondrial ) is also named as IPOB, MNSOD, SODM, Mn-SOD and belongs to the iron/manganese superoxide dismutase family. It is a marker of mitochondria, which is restricted to the perinuclear area in a cell with aggregate formation of mutant SOD1. It functions as the first line of antioxidant defense against highly reactive superoxide radicals and it appears to be early predictors for survival in septic patients with with MIF. It has 2 isoforms with the molecular weight of 25 kDa and 21 kDa.

Bombesin is a 14-aa peptide originally isolated from the fire-bellied toad. It has two mammalian homologs, neuromedin and Gastrin-Releasing Peptide (GRP). It binds with high affinity to the GRP receptor, a member of the G-protein-coupled receptor family. It stimulates gastrin release from G cells, and acts in the brain to stop eating behavior.
Bombesin is also a tumor marker for lung small cell carcinoma, neuroblastoma, pancreatic cancer and gastric cancer.

This mAb recognizes basic (Type II or HMW) cytokeratins, which include 67kDa (CK1); 64kDa (CK3); 59kDa (CK4); 58kDa (CK5); 56kDa (CK6); 52kDa (CK8). Twenty human keratins are resolved with two-dimensional gel electrophoresis into acidic (pI 6.0) subfamilies. The acidic keratins have molecular weights (MW) of 56.5, 55, 51, 50, 50 , 48, 46, 45, and 40kDa. Many studies have shown the usefulness of keratins as markers in cancer research and tumor diagnosis.

This Epithelial Membrane Antigen / EMA antibody, also called MUC1 and Mucin-1, recognizes the full-length protein in a glycosylation-independent manner and can bind to the fully glycosylated protein. The dominant epitope of this mAb is APDTR in the VNTR region. It reacts with the core peptide of the EMA protein, which is a member of a family of mucin glycoproteins that are characterized by high carbohydrate content, O-linked oligosaccharides, high molecular weight (>200kDa) and an amino acid composition rich in serine, threonine, proline and glycine. The core protein contains a domain of 20 amino-acid tandem repeats that functions as multiple epitopes for the mAb. Incomplete glycosylation of some tumor-associated mucins may lead to variable unmasking of the multiple peptide epitopes leading to the observed differences in staining intensity between normal and malignant tissues. This EMA antibody reacts with both normal and malignant epithelia of various tissues including breast and colon.
