Description: 14-3-3 proteins are a family of small, evolutionarily conserved proteins which display various wide-ranging functions. 14-3-3 isoforms are found in all vertebrates, invertebrates, plants and fungi. These have been classified in mammalian species as typical (gamma, eta, beta/alpha, zeta/delta, t) or atypical (sigma and epsilon) isoforms, based on their distribution and apparent functional roles. While 14-3-3 isoforms are expressed at ubiquitous, low levels in most human tissues, all 14-3-3 isoforms (with the exception of sigma) are primarily expressed in neurons. 14-3-3 proteins are highly enriched in areas of neuronal death associated with Alzheimer's disease and have been reported as a marker for this disease. 14-3-3sigma, which inhibits the activity of Cdc25C. In response to DNA damage, Cdc25C binds to 14-3-3sigma, which inhibits the activity of Cdc25C and results in G2 cell cycle arrest. In addition, 14-3-3 may play a role in apoptosis via binding to the pro-apoptotic molecule, BAD. 14-3-3 isoforms have molecular masses of ~30 kDa on SDS-PAGE. C23-1 reacts with human 14-3-3. Full length, recombinant human 14-3-3 was used as immunogen. The C23-1 clone recognizes a 14-3-3 isoform of ~31 kDa on SDS-PAGE. The identity of this isoform has not been characterized.

Characteristics: 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Please refer to us for technical protocols.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
