Depositors Notes: 4C9H4 is an excellent marker for cytokinesis, and labels the cleavage furrow of dividing embryonic and imaginal disc cells. It recognizes the product of the peanut gene, which encodes a protein similar to the bud neck filament proteins of S. cerevisiae (CDC3, CDC10, CDC11 and CDC12).
Immunogen: GST-fusion protein containing the amino-terminal 116 aa of the peanut protein.
Alternate Gene Names: CG8705
Immunogen Sequence: Partial protein
Isotype: MIgG1, kappa light chain
Alternate Antibody Name: 4C9
Alternate Antigen Name:
Epitope Mapped: Yes
Myeloma Strain: P3x63Ag8.653
Epitope Location or Sequence: amino-terminal 116 aa
Recommended Applications: Immunofluorescence, Immunoprecipitation, Western Blot

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable.
To ensure retention of antibody activity, we recommend aliquotting the product into two parts:
1) a volume of antibody stored at 4°C to be used within two weeks.
2) the remaining product diluted with an equal volume of molecular grade glycerol and stored at -20°C.
While optimal Ig concentration for an application will vary, a good starting concentration for immunohistochemistry (IHC),
immunofluorescence(IF) and staining is 2-5 µg/ml.
For Western blots, the concentration is decreased by one order of magnitude (that is, 0.2-0.5 µg/ml).
All cell products contain the antimicrobial ProClin. See our FAQ section for additional information.
