商品信息

This assay kit contains all the reagents for cytolocalization of human, p170 topo II using immunofluorescence.? The system is optimized for use with FITC or Rhodamine labeled

secondary antibody with adherent cells.? The method may work with other cells besides human. Mouse, rat and monkey cells will cross react with topo II antibody.? The antibody is specific for p170 (topo II alpha).

Kit Contents:


1


Anti-topo II (p170) Antibody
(TG2011-1).? This is a rabbit antibody (polyclonal) directed against the C-Terminal region of p170.? A peptide was used to raise this antiserum; the antibody has been immunoaffinity purified.? Kit contains 100 ul of antibody.



2


Peptide reagent:
(TG2011-2). A total of 50 ug (at 2 mg/ml) of peptide included. The seqeunce is the C-terminal 16 amino acid residues in p170. This peptide is in sodium phosphate buffer.

Detailed Manual of Operation

sh peroxidase staining will require some modifications worked out by the investigator.? It is important to note that because topo II is highly enriched in chromosomes, an internal control is built into the method; one should see brightly fluorescent chromosomes (in mitotic cells of course).

Controls and Important Considerations


1


As noted above
topoisomerase II has a characteristic distribution pattern in cells that clearly indicates whether the procedure is working. In interphase cells, the pattern of distribution of topo II is almost totally nuclear and appears to be punctiform or pin-point in nature.? The signal is clearly amplified in metaphase cells when chromosomes are vis
IBL
e.? There should be about a 5-10 fold increase in fluorescent intensity in the latter cells.

2


The peptide that is included
is an important control reagent.? Incubating the cells with peptide plus primary topo II antibody should neutralize the fluorescent signal.
