This SMARCAL1 / HARP antibody was raised against purifed bovine SMARCAL1 / HARP protein.


Purified IgG in 70 mM Tris (pH 8), 105 mM NaCl, 31 mM glycine, 0.07 mM EDTA, 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.



SMARCAL1 / HARP (SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily A-like protein 1, HepA-related protein, DNA-dependent ATPase A) is a member of the SWI / SNF family of ATPases and chromatin remodeling proteins. Unlike other SWI / SNF family members, SMARCAL1 / HARP has not been shown to remodel chromatin, but possesses an ATP-dependent annealing helicase activity. SMARCAL1 reanneals single-stranded DNA bubbles in DNA at DNA replication forks that are bound by Replication Protein A (RPA). Defects in SMARCAL1 / HARP are a cause of Schimke immuno-osseous dysplasia (SIOD) SIOD causes spondyloepiphyseal dysplasia (a disorder of bone growth that results in short stature, skeletal abnormalities, and problems with vision and hearing), renal dysfunction and T-cell immunodeficiency.

Bridging Antibody to Improve ChIP, MeDIP and IP

Some isotypes of mouse IgG antibodies do not bind well to protein G-conjugated agarose/magnetic beads, which are commonly used in ChIP, MeDIP and IP experiments. Capture efficiency can be improved by including an anti-mouse IgG bridging antibody because it binds with a strong affinity to both the protein G beads and the mouse IgG antibody. By increasing the affinity of the mouse primary antibody for the protein G bead, the Bridging Antibody for Mouse IgG can help improve the results of all ChIP, MeDIP and IP experiments that use SMARCAL1 / HARP antibody (mAb).


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
