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.


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. Peters primary focus is the customer experience and he will be working with the Laboratory team, the Quality Control team and the Order Processing team to ensure this focus is achieved. We all wish Peter well in his new role.

Price (USD)



May serve as a flippase as well as a glucosyltransferase that transfers glucose to ceramide. It Catalzes; UDP-glucose + N-acylsphingosine = UDP + D-glucosyl-N-acylsphingosine. Ceramide Glycosyltransferase is the first step in the Glycosphingolipid synthesis; first glycosylation step. Glucosylceramide synthase (GlcT) and lactosylceramide synthase (GalT) are key enzymes for the synthesis of major glycosphingolipids of vertebrates.


Synthetic peptide derived from human ceramide glycosyltransferase protein.

Positive Control

Found in all tissues examined.


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

Customer Storage

Product should be stored at -20°C. Aliquot to avoid freeze/thaw cycles
