Ki67, also known as MKI67, it is the prototypic cell cycle related nuclear protein, expressed by proliferating cells in all phases of the active cell cycle (G1, S, G2 and M phase). It is absent in resting (G0) cells. Ki67 antibodies are useful in establishing the cell growing fraction in neoplasms (immunohistochemically quantified by determining the number of Ki67 positive cells among the total number of resting cells = Ki67 index). In neoplastic tissues the prognostic value is comparable to the tritiated thymidine labelling index. The correlation between low Ki67 index and histologically low grade tumours is strong. Ki67 is routinely used as a neuronal marker of cell cycling and proliferation.

Ractopamine is a phenolethanolamine ß-adrenoceptor agonist that is used for the improvement of weight gain, carcass leanness and feed efficiency in pigs. It has been known for years that ractopamine enhances growth in meat animals by repartitioning nutrients. This means that the nutrients that the animal consumes in its feed are shifted away from being stored as fat and are instead used in lean tissue production. This shift occurs as the animal reaches the top of its growth curve and lean tissue production drops off and fat deposition increases. Fat levels also appear to decrease, due to an increase in lypolysis (fat breakdown). Using the ractopamine monoclonal antibody, it is possible to detect ractopamine and other agonists in urine, muscle and liver both rapidly and with accuracy.
This gene encodes a serine protease. The protein has been localized in the endoplasmic reticulum and interacts with an alternatively spliced form of mitogen-activated protein kinase 14. The protein has also been localized to the mitochondria with release to the cytosol following apoptotic stimulus. The protein is thought to induce apoptosis by binding the apoptosis inhibitory protein baculoviral IAP repeat-containing 4. Nuclear localization of this protein has also been observed. Alternate splicing of this gene results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2016]

CD117 is a cell membrane protein encoded by the c-kit proto-oncogene. CD117 is expressed in mast cells, skin melanocytes and interstitial Cajal cells (ICC). These cells show a strong membrane and cytoplasmic staining. CD117 is also expressed in various epithelia (salivary glands, renal tubular cells etc.). Appendix serves as a good positive and negative control tissue. Neoplasms such as gastrointestinal stromal tumor (GIST), mast cell neoplasms and many other (seminoma, Mercel cell carcinoma etc.) express CD117. This antibody (together with DOG-1, CD34, SMA) is of great importance in the diagnosis of GIST, because of specific treatment of GIST patient with Gleveec.
Calretinin is a calcium-binding protein and it is expressed in neurons and in nervous system. Calretinin is also expressed in mesothelial cells and steroid producing cells eg. Leydig cells and adrenal cortical cells as well as fat cells and some neuroendocrine cells. Calretinin located in the cells to nucleus and cytoplasm. Calretinin is useful for mesothelioma diagnostic (differentiate diagnostic between mesothelioma from carcinoma) and it is expressed in most malignant mesothelioma.
SOX2 is a transcription factor which is a member of SRY-related HMG-box (SOX) family. It has a role in the regulation of embryonic development and pluripotency of stem cells. It can be useful especially in lung squamous cell carcinoma diagnostic with panel of other relative markers of squamous carcinoma like P63/P40 and CK5/CK14 for example.
Mismatch repair proteins are nuclear enzymes which participate in repair of mismatch errors during DNA replication. Loss of Mismatch repair proteins increases the number of DNA replication errors in the proliferating cells. Errors occur especially in areas of the genome with short repetitive nucleotide sequences - causing microsatellite instability (MSI). MSH6 is a mismatch repair protein which is not expressed in a high proportion of patients with MSI-H. MSH6 antibody can be useful for immunohistochemical analyses of MSH6 protein in neoplastic tissues and identification of loss of MSH6. Immunohistochemical analysis of MSH6 should be performed in IHC panel together with MLH1, MSH2 and PMS2.
Cell adhesion molecule with an important role in the development of the nervous system. The L1, neural cell adhesion molecule (L1CAM) plays an important role in axon growth, fasciculation, neural migration and in mediating neuronal differentiation. L1 protein is expressed to tissues arising from neuroectoderm. L1CAM plays also an important role in the malignancy of human tumors and according to several studies, L1CAM positive carcinomas have a bad prognosis. L1CAM is overexpressed in many human carcinomas but it is useful especially in endometrium carcinoma diagnostic.
Cytokeratin 18, also known as CK18, CYK18, KRT18. Entrez Protein NP_000215. It encodes the type I intermediate filament chain keratin 18. Keratin 18, together with its filament partner keratin 8, are perhaps the most commonly found members of the intermediate filament gene family. They are expressed in single layer epithelial tissues of the body. Mutations in this gene have been linked to cryptogenic cirrhosis. Two transcript variants encoding the same protein have been found for this gene.
Synaptophysin (p38) is an integral membrane protein of small synaptic vesicles in brain and endocrine cells.Synaptophysin contains four transmembrane domains that form a hexameric channel or gap junction-like pore. Synaptophysin binds to the SNARE protein synaptobrevin/VAMP, which prevents the inclusion of synaptobrevin in the synaptic vesicle fusion complex and creates a pool of synaptobrevin for exocytosis when synapse activity increases. Synaptophysin is also responsible for targeting synaptobrevin 2/VAMP2 to synaptic vesicles, a critical component of the fusion complex.
