Product Information

Product Usage Information

This product is the carrier-free version of product #72364. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN, or CUT&Tag assays. If you require a carrier-free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

Formulation

Supplied in 1X PBS, BSA and Azide Free.

For standard formulation of this product see product #72364.

Storage

Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

Specificity / Sensitivity

SS18-SSX (E9X9V) XP® Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total SS18-SSX fusion protein. This antibody does not cross-react with wild-type SS18 or SSX proteins.

Species Reactivity:

Human

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding the fusion site of human SS18-SSX protein.

Background

SS18 is a protein that has been shown to be a part of the SWI/SNF complex (1, 2). The SS18-SSX fusion proteins are a result of in-frame fusions that fuse the SS18 gene on chromosome 18 with X chromosome genes SSX1, SSX2, and to a lesser extent SSX4 (3). Human synovial sarcoma (SS) accounts for 8-10% of all soft tissue malignancies and 95% of these malignancies express the recurrent translocation of the SS18 gene on chromosome 18 (3). The N-terminal SNH domain (SYT N-terminal homology domain) of the SS18 protein interacts with SWI/SNF chromatin remodeling complexes via the N terminal region of BRM and BRG1 subunits (4). Studies of the SS18-SSX fusion in SS suggest that endogenous SS18 competes with the mutant SS18-SSX fusion for occupancy in the SWI/SNF complexes resulting in the displacement of SNF5 (BAF47) subunit. Displacement of the SNF5 subunit results in altered function of the SWI/SNF complex that leads to deregulated expression of genes such as Sox2 in SS (3).

SS18-SSX (E9X9V) XP® Rabbit mAb (BSA and Azide Free)

Western Blotting Image 1: SS18-SSX (E9X9V) XP® Rabbit mAb (BSA and Azide Free) Expand Image
Western blot analysis of extracts from various cell lines using SS18-SSX (E9X9V) XP® Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower). ASKA is a synovial sarcoma cell line with an SS18-SSX1 fusion, while SYO-1 is a synovial sarcoma cell line with an SS18-SSX2 fusion. As shown, SS18-SSX (E9X9V) XP® Rabbit mAb only detects the fusion protein and not WT proteins. Cell lysates were isolated and provided by the Kadoch laboratory. Data were generated using the standard formulation of this product.
