Protein ladder western blot bio rad12/11/2023 ![]() IEF standards: use 5 µl per mini gel for Coomassie staining or 0.5 µl for silver staining to yield 50 or 500 applications, respectively. Western blotting is a powerful technique that allows you to positively detect your proteins, estimate quantities, and determine their molecular weights. * 2-D standards: use 2.5 µl per mini gel for Coomassie staining (200 applications) or 0.5–2.5 µl for silver staining (up to 1,000 applications) use 1.0–5.0 µl for full-length gels (16–20 cm) to yield 100 or up to 500 applications, respectively. 2-D SDS-PAGE protein standards provide calibrated references for protein pI and molecular weight in the second dimension. IEF and 2D protein standards are a mixture of native proteins with isoelectric points (pI) ranging from 4.45 to 9.6, providing reproducible pI calibration in native PAGE or agarose IEF gels. When detecting and quantifying low abundant proteins Bio-Rad recommends customers develop the blots using Bio-Rads Clarity Western ECL Substrate which has long. ![]() We also provide a list of reagents that work optimally with our antibodies. IEF and 2D Electrophoresis Protein Standards Detection of Phosphorylated Proteins by Western Blotting WB This protocol describes how to detect phosphorylated proteins by western blotting using Phospho-Specific PrecisionAb Antibodies. The traditional method to visualize protein ladders on Western blots is to use prestained protein ladders which remain visible when transferred to the blotted membrane. ![]()
