Product Highlight

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

Mouse PRL-2, also known as Protein tyrosine phosphatase 4a2 (Ptp4a2) is a unique nuclear protein tyrosine phosphatase (PTP) that plays a central role in regulating diverse cellular processes. PRL-1 is induced in mitogen-stimulated cells and regenerating liver. Mouse PRL-2 exhibit 87% identity to mouse PRL-1 in their amino acid sequences. All mouse PRL proteins contain a C-terminal consensus sequence for prenylation. All PRL proteins bear significant sequence homology to Cdc14p and the tumor suppressor PTEN/MMAC1. PRL-2 is preferentially expressed in skeletal muscle. PRL-2 is also expressed at lower levels in other tissues
