Product Description

14-3-3 sigma was identified as an epithelial cell marker. It is part of the 14-3-3 family of proteins in which seven isoforms have been identified: beta, zeta, gamma, eta, epsilon, tau, and sigma. 14-3-3 proteins function as adaptors that bind with a number of partners to mediate various signaling pathways. 14-3-3 sigma is also called stratifin or HME1 and appears to function as a tumor suppressor whose expression can be downregulated via methylation. Loss of 14-3-3 sigma expression results in a defective G2/M phase checkpoint and appears to contribute to both epithelial and non-epithelial tumorigenesis.

Production & Epitope

Antibody was affinity purified using an epitope specific to 14-3-3 Sigma immobilized on solid support.

The epitope recognized by A301-648A maps to a region between residue 198 and 248 of human 14-3-3 sigma using the numbering given in entry NP_006133.1 (GeneID 2810).

Immunoglobulin concentration was determined using Beer’s Law where 1mg/mL IgG has an A280 of 1.4.

Applications

All western blot analysis is performed using 5% Milk-TBST for blocking and as antibody diluent. Primary antibody is incubated overnight.

Western blots of cell lysates are performed using Goat anti-Rabbit IgG Heavy and Light Chain Antibody (A120-101P).

Western blots of immunoprecipitates are performed using an anti-Rabbit IgG Light Chain HRP-conjugated antibody with 5% Normal Pig Serum (Cat. No. S100-020) added to the blocking buffer.

Immunohistochemistry (IHC)1:2000 to 1:10,000. Epitope retrieval with citrate buffer pH6.0 is recommended for FFPE tissue sections.
Immunoprecipitation (IP)6 µg/mg lysate
Western Blot (WB)1:10,000 - 1:25,000
