The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/250 - 1/500.
1/500 - 1/1000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
Use a concentration of 1 - 4 µg/ml. Fixation/Permeabilization: PFA/Triton X-100
FunctionProbable regulator of sister chromatid cohesion in mitosis which may stabilize cohesin complex association with chromatin. May couple sister chromatid cohesion during mitosis to DNA replication. Cohesion ensures that chromosome partitioning is accurate in both meiotic and mitotic cells and plays an important role in DNA repair.
Tissue specificityHighest level in colon. Low levels in lung, ovary, breast and kidney. Reduced level in renal tumor tissue. Isoform 2 is expressed in kidney.
Sequence similaritiesBelongs to the PDS5 family. Contains 1 HEAT repeat.
Developmental stageCell cycle-regulated with highest level in G2 phase.
Cellular localizationNucleus. Associated with chromatin through most of the cell cycle. Dissociates from chromatin in late prophase, reassociates during late telophase.
