SRPX Antilichaam / Sushi repeat-bevattende proteïne X-linked

Western Blot: 0.25-0.5 µg/mL, ELISA: 0.1-0.5 µg/mL

P78539

Human

E.coli-derived human SRPX recombinant protein (Position: E40-T464) was used as the immunogen for the SRPX antibody.

WB, ELISA

Immunogen affinity purified

Lyophilized

Each vial contains 4 mg Trehalose, 0.9 mg NaCl, 0.2 mg Na2HPO4.

This SRPX antibody is available for research use only.

After reconstitution, the SRPX antibody can be stored for up to one month at 4°C. For long-term, aliquot and store at -20°C. Avoid repeated freezing and thawing.

Adding 0.2 ml of distilled water will yield a concentration of 500 ug/ml

Optimal dilution of the SRPX antibody should be determined by the researcher.

Western blot analysis of SRPX using anti-SRPX antibody. Electrophoresis was performed on a 10% SDS-PAGE gel at 80V (Stacking gel) / 120V (Resolving gel) for 2 hours. Lane 1: human U251 whole cell lysates, Lane 2: human U2OS whole cell lysates, Lane 3: human PC-3 whole cell lysates, Lane 4: human 293T whole cell lysates. After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-SRPX antibody at 0.5 ug/ml overnight at 4oC, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal was developed using an ECL Plus Western Blotting Substrate. A predominant band is detected between an approximately 65 and 70 kDa in all samples, running above the predicted ~52 kDa polypeptide mass but consistent with the higher apparent molecular weight expected for the heavily glycosylated secreted protein SRPX.
