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.

News

Welcome, Peter Rutten

We are pleased to announce that Peter Rutten has now started in his role as Operations Director here at Exalpha Biologicals Inc. Peter has a Master’s of Science degree in Industrial and Organizational Psychology and this has lead him down a very business orientated career path. Peter is looking forward to working with the team at Exalpha.

Background

CD54, M.W. 90,000, antigen is the Intercellular Adhesion Molecule-1 (ICAM-1) and is the ligand for LFA-1 mediated adhesion. CD54 is weakly expressed on peripheral blood leukocytes. Upon activation the antigen is expressed strongly on B cells, T cells, macrophages and granulocytes. ICAM-1 is also inducible on endothelial cells, epithelial cells and fibroblasts.

Immunogen

CD54=Derived from the hybridization of mouse NS-1 myeloma cells with spleen cells from BALB/c mice immunized with the major histocompatibility complex (MHC) class II-negative human b-lymphoblastoid cell line 6.16c13

Formulation

Provided as solution in phosphate buffered saline with 0.08% sodium azide
