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.

About

Exalpha was founded over 20 years ago by a group of scientists dedicated to accelerating the pace of discovery in the life science arena by rapidly developing and marketing unique products at the forefront of science.

In order to develop great products, you have to ask the right questions when you start. Where some companies are satisfied with ‘average’, ‘good enough’ or ‘me too’ products, Exalpha only settles for products that answer the pertinent questions. Exalpha continually monitors scientific trends and recent literature, we strive to produce products that answer real needs.  Exalpha has a long history of developing uniquely superior products that simply perform well, allowing researchers to focus on the task at hand and not on the quality of a supplier’s products.
