![]() ![]() Mix the Clarity Western ECL Substrate Kit components in a 1:1 ratio. It is important to use an ECL substrate that has good sensitivity and long signal duration, such as the Clarity Western ECL Substrate. Trans-Blot SD Semi-Dry Electrophoretic Transfer Cell (Bio-Rad, P/N 170-3940). After the final wash step, keep the blot in TBST while preparing for blot detectionĪll PrecisionAb Antibodies were validated using enhanced chemiluminescent (ECL) detection. first with each individual antibody to be certain of expected band sizes. Rinse the blot with 15 ml TBST at RT for 5 min. There are several ways to identify the presence of the abnormal prion protein - a bioassay, immunohistochemistry on diseased tissue samples, and with a faster, well-characterized, and sensitive Western blot. Incubate the blot in the secondary antibody and blocking buffer solution at RT for 1 hr with gentle agitation Please refer to the antibody product page for details on the exact secondary antibody used during the validation process. Repeat for a total of five washesĭilute the appropriate secondary antibody in 10 ml blocking buffer according to the following table: Rinse the blot with 15 ml TBST at RT for 5 min. Incubate the blot in the primary antibody and blocking buffer solution at 4☌ overnight with gentle agitation Please see the validation protocol (bulletin 6603) for more details.ĭilute the primary antibody 1:1,000 in 10 ml blocking buffer If using BSA, you may notice some nonspecific bands due to its low stringency. Powerful software package for acquisition and analysis. We recommend using casein or nonfat dried milk for blocking. When using casein, do not block for longer than 30 min to prevent reduction in signal specificity. In the western blot image, visible decrease in ATG5 protein band intensity was seen. Load the control cell lysate adjacent to your samples and the molecular weight (MW) marker (see diagram).ĭuring the validation process, we blocked for 30 min at room temperature (RT) in blocking buffer + 0.1% Tween 20. 1620174) TransBlot Turbo Mini-size LF PVDF membranes (Bio-Rad cat. If using BME, add 180 μl H20, 200 μl 2x Laemmli Sample Buffer, and 20 μl BME If using DTT, add 190 μl H20, 200 μl 2x Laemmli Sample Buffer, and 10 μl 2 M DTT Reconstitute 400 µg lysate in one of the following ways, depending on the reducing reagent used: Secondary antibodies (see antibody datasheet) Trans-Blot Turbo Mini PVDF Transfer Pack.Transfer membranes, reagents, and equipment 1x Tris/glycine/SDS (TGS running buffer).Precision Plus Protein All Blue Standards Value Pack.Mini-PROTEAN Tetra Cell for Mini Precast Gels.Any kD Mini-PROTEAN® TGX Stain-Free Precast Gels (10 well, 50 µl).4–15% Mini-PROTEAN® TGX Stain-Free Precast Gels (10 well, 50 µl).Phosphate Buffered Saline (PBS) containing 1% w/v BSA ![]() Reducing agents such as dithiothreitol (DTT) or ß-mercaptoethanol (BME)Įlectrophoresis gels, reagents, and equipment ![]()
