Omschrijving: β-Pseudouridine isomer of the nucleoside uridine found in all species and in many classes of RNA except mRNA. It is formed by enzymes called Ψ synthases, which post-transcriptionally isomerize specific uridine residues in RNA in a process termed pseudouridylation. Studies suggest that β-Pseudouridine reduces radiation-induced chromosome aberrations in human lymphocytes.

Omschrijving: Cytokines for expansion and cell culture of mouse hematopoietic stem cells. Hematopoietic stem cells are self renewing pluripotent cells often characterized by the expression of CD34. Studies have shown that decreased expression of CD34 tends to correlate with decreased self renewal properties and pluripotent potential. Culturing CD34+ cells in a cytokine mixture of TPO, SCF, and FLT-3 Ligand for short time periods allows CD34+ cells to proliferate without decreasing CD34 expression, thus retaining their stem cell properties.

Omschrijving: Cytokeratins, a group comprising at least 29 different proteins, are characteristic of epithelial and trichocytic cells. Cytokeratins 1, 4, 5, 6, and 8 are members of the type II neutral to basic subfamily. Antibody to cytokeratins are specific markers of epithelial cell differentiation and have been widely used as tools in tumor identification and classification. Anti Pan Cytokeratin (mixture) is a broadly reactive reagent, which recognizes epitopes present in most human epithelial tissues. It facilitates typing of normal, metaplastic and neoplastic cells. Synergy between the various components results in staining amplification. This enables identification of cells, which would otherwise be stained only marginally. The mixture may aid in the discrimination of carcinomas and nonepithelial tumors such as sarcomas, lymphomas and neural tumors. It is also useful in detecting micrometastases in lymph nodes, bone marrow and other tissues and for determining the origin of poorly differentiated tumors. There are two types of cytokeratins the acidic type I cytokeratins and the basic or neutral type II cytokeratins. Cytokeratins are usually found in pairs comprising a type I cytokeratin and a type II cytokeratin. Usually the type II cytokeratins are 8kD larger than their type I counterparts.

Omschrijving: 5-(and-6)-FAM (full name: 5-(and-6)-Carboxyfluorescein mixed isomer) has a pKa of 6.5 and can be used as a pH indicator. Its excitation spectrum and fluorescence response to pH are similar to those of BCECF. Carboxyfluorescein can also be used as a tracer dye. The dye is membrane-impermeant and can be loaded into cells by microinjection or scrape loading.
