Specificity / Sensitivity

SGO2 (E9K4N) Rabbit mAb recognizes endogenous levels of total SGO2 protein. Based on the sequence of the immunogenic peptide, this antibody is expected to recognize isoforms 1-3 of human SGO2 protein.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly15 of human SGO2 protein.

Background

SGO2 (Shugoshin-2, SGOL2) is a centromeric protein required for the protection of cohesion complexes in meiosis (1). In mitosis, SGO2 and MAD2 regulate separase activity in the absence of securin to ensure appropriate timing of chromosome segregation (2). SGO2 is highly expressed in prostate cancer, and it promotes proliferation and migration by stabilizing the small GTPase Rab1A (3). High SGO2 expression in hepatocellular carcinoma (HCC) predicts poor overall survival (4), promoting tumor proliferation by regulating MAD2 expression and function (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

Western Blotting Image 1: SGO2 (E9K4N) Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using SGO2 (E9K4N) Rabbit mAb (upper) or GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). Low expression of SGO2 protein in Caki-1 cells is consistent with the predicted expression pattern.
Immunoprecipitation Image 1: SGO2 (E9K4N) Rabbit mAb Expand Image
Immunoprecipitation of SGO2 protein from RKO cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is SGO2 (E9K4N) Rabbit mAb. Western blot analysis was performed using SGO2 (E9K4N) Rabbit mAb. Anti-rabbit IgG, HRP-linked Antibody #7074 was used as a secondary antibody.
