  • FunctionPlays an important role in the organization of the cytoskeleton (By similarity). Binds to and sequesters actin monomers (G actin) and therefore inhibits actin polymerization.
    Seraspenide inhibits the entry of hematopoeitic pluripotent stem cells into the S-phase.
  • Tissue specificityExpressed in several hemopoietic cell lines and lymphoid malignant cells. Decreased levels in myeloma cells.
  • Sequence similaritiesBelongs to the thymosin beta family.
  • Cellular localizationCytoplasm > cytoskeleton.

Anti-Thymosin beta 4 antibody images

  • ICC/IF image of ab14335 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab14335, 1/200 dilution) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
