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

Influenza virus is a single-stranded RNA virus, segmented, 70nm in diameter and enveloped. Strains are described by geographic origin, strain number, year of isolation and hemagglutination (H) and neuraminidase (N) antigens.

Immunogen

Recombinant full-length H1N1 A/New Caledonia/20/99 (MW 72kD) is glycosylated with N-linked sugars and produced using baculovirus vectors in insect cells. The insect cells were infected with A9440.1a, recombinant baculovirus expressing recombinant H1N1 A/New Caledonia/20/99. H1N1 New Caledonia shows 90% similarity to the A/PR/8/34 amino acid sequence.

Positive Control

Recombinant full-length H1N1 A/New Caledonia/20/99 (MW 7.5kD) is glycosylated with N-linked sugars and produced using baculovirus vectors in insect cells. The insect cells were infected with A9440.1a, recombinant baculovirus expressing recombinant H1N1 A/New Caledonia/20/99. H1N1 New Caledonia shows 90% similarity to the A/PR/8/34 amino acid sequence.
