Ab169639

Manufactured by Abcam
Sourced in United States

Ab169639 is a primary antibody that recognizes the SWI/SNF-related matrix-associated actin-dependent regulator of chromatin subfamily A member 5 (SMARCA5) protein. SMARCA5 is a DNA-dependent ATPase that is a component of the ISWI chromatin remodeling complex. This antibody can be used for applications such as Western blotting and immunohistochemistry.

Preparation and immunostaining of cells was performed using standard protocol as described [34 (link)]. The primary antibody used was anti-Coilin (1:2000; Ff-7, mouse sc-55594, Santa Cruz, USA)), anti-PARG (1:1000; rabbit, ab169639, Abcam, USA), and the secondary antibody used was goat anti-rabbit Alexa-563 (1:400, Molecular Probes, USA) and anti-mouse Alexa-488 (1:400, Molecular Probes, USA). Slides were mounted in Vectashield (Vector Laboratories, Burlingame, CA, USA) with Draq5 dye (424101, BioLegend, USA) at 0.05 mg/ml for DNA staining.

For semi-quantitative protein analysis, cells were lysed in 1xSDS sample buffer (25 mM Tris (pH 6.8), 2% 2-mercaptoethanol, 3% SDS, 0.1% bromophenol blue, and 5% glycerol) at 1 × 107 cells/ml and then boiled for 5 min. Proteins were resolved by SDS-PAGE and transferred to i-Blot (IB23001, Invitrogen, USA). The following antibodies were used for immunoblotting assays: anti-pADPr (1:4000, rabbit, 528815, Calbiochem, USA), anti-pADPr (1:500, mouse, 1020, Tulip Biolabs, USA), anti-hPARG (1:1000; rabbit, ab169639 Abcam, USA), anti PSA (1:1000, rabbit, 5153, Cell Signaling Technology, USA), anti-β-actin (1:5000, mouse, A5441, Sigma, USA), anti-GFP (1:1000, rabbit, TP401, Origene, USA), anti-GFP (1:5000, mouse, 632380, BD, USA), and either goat anti-rabbit or anti-mouse secondary antibody conjugated to horseradish peroxidase (Sigma, USA). Western blotting was done using the detection kit from Amersham/GE Healthcare (RPN2106, USA), according to the manufacturer’s instructions. Image digitizing and quantitative analysis were performed by Odyssey v1.2 software (LI-COR, Lincoln, NE, USA).

The Human ON-TARGETplus siRNA Library-DNA Damage Response and the siRNA targeting OGG1, PARG, Pol β, and XRCC1, each containing a pool of four different siRNA sequences to help aid knockdown efficiencies, were from Horizon Discovery (Cambridge, UK). The non-targeting control siRNA (AllStars Negative Control siRNA) was from Qiagen (Manchester, UK). The following antibodies were used: γH2AX (05–636; Merck-Millipore, Watford, UK), OGG1, PARG, phosphorylated ATM and phosphorylated DNA-PKcs (ab124741, ab169639, ab81292 and ab18192; Abcam, Cambridge, UK), PARP-1 (sc-53643; Santa Cruz Biotechnology, Heidelberg, Germany), OGG1 for immunofluorescence (NB100-106; Bio-Techne Ltd, Abingdon, UK), Polβ and XRCC1 (kindly provided by G. Dianov) and tubulin (T6199; Sigma-Aldrich, Gillingham, UK). Goat anti-mouse Alexa Fluor 555 or goat anti-rabbit Alexa Fluor 488 secondary antibodies for immunofluorescence were from Life Technologies (Paisley, UK). The OGG1 inhibitor TH5487, as previously described [21 (link)], was used at a concentration of 10 µM. The PARG inhibitor PDD00017273, also previously described [22 (link)], was used at a concentration of 1 µM.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
