FIX&PERM Cell Fixation and Permeabilization Kit

Flow cytometric analyses with monoclonal antibodies were so far mainly restricted to cell surface molecules. Intracellular structures such as cytoplasmic or nuclear enzymes, oncoproteins, cytokines, immunoglobulins etc. were largely excluded from such studies. Also excluded from flow cytometric studies were cytoplasmic localizations of well-established membrane molecules like CD3 and CD22, which, in their cytoplasmic form, are the most reliable lineage markers in undifferentiated leukemia. With the FIX&PERM® Kit flow cytometric analysis of intracellular antigens has become as easy as surface antigen studies. The only prerequisite is the availability of suitable antibody conjugates. Most of the available monoclonal antibody conjugates can be used with the FIX&PERM® Kit, some determinants are sensitive, however, to the fixation step involved. This and the optimal fixation time have to be tested for each reagent.

Background

CD27 (Cluster of Differentiation 247) is a tumor necrosis factor receptor. A tumor necrosis factor receptor (TNFR), or death receptor, is a trimeric cytokine receptor that binds tumor necrosis factors (TNF).. The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor is required for geneRation and long-term maintenance of T cell immunity. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis. The immune system has several effector mechanisms at its disposal to free the host of pathogens. Because these effector mechanisms can also damage the host, immune responses should be tightly controlled. TNFR family members and their respective TNF related ligands have been impliCated in the regulation of survival, prolifeRation, differentiation, and migRation during adaptive immune responses. CD27 is a lymphoid cell-specific member of the TNFR family. Human and murine T, B, and NK cells can express CD27 In Humans, CD27 expression distinguishes between naive and effector/memory stages of peripheral B and T lymphocytes. On B cells, CD27 is only found after B cell receptor-induced activation. CD27-expressing B cells found in Human peripheral blood all have undergone somatic hypermutation and therefore CD27 is considered a marker for memory B cells in Humans. Resting T cells constitutively express CD27, while differentiation into effector T cells is accompanied by loss of CD27 expression.
