![]() ![]() For special cases, use the Chameleon Kit to customize a two-color protein ladder that suits the needs of your experiment. Chameleon Duo can be used to perform two-color visible and near-infrared detection. ![]() Not intended for human or animal diagnostic or therapeutic uses. Chameleon 700 or Chameleon 800 protein ladders can be used for one-channel analysis. e ladder proteins can be detected by Coomassie Blue staining of SDS-PAGE gels and on Western blots through engineered IgG binding domains. The apparent molecular weight (kDa) of each protein has been determined by calibration against unstained protein standards supplemental data should be considered for more accurate adjustment in different electrophoresis conditions. New England Biolabs offers a selection of highly pure protein standards. by metal anity chromatography with minimal equipment. ![]() Under suggested conditions, Unveil Unstained Protein Ladder resolves 12 major bands in 4-12%Bis- Tris Gel(MES buffer) and after Western blotting to the nitrocellulose membrane. 2.5 μl per well for general Western transferring.Ģ0 mM Tris-phosphate(pH 7.5 at 25☌), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol. Get more from your multiplex westerns Fluorescent. We offer optimized reagents, buffers and fluorescent conjugated antibodies so you can get the most from your fluorescent western blots. The ladder is supplied in the gel loading buffer and is ready to use.ģ μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively. Fluorescent western blotting provides accurate, quantitative, stable signals, and the ability to clearly evaluate multiple protein targets on a single blot. Choosing the right gel is a key factor in the successful transfer of HMW proteins. The Unveil Unstained Protein Ladder is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis and verifying Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. Choose from a variety of protein ladders (molecular weight markers) for protein electrophoresis and western blotting applications. Make sure sample preparation conditions have not destroyed the antigenicity of the sample. What this means is that before even loading the ladders into the gel for electrophoresis, these ladders are previously stained and ready to go. The proteins resolve into clearly identifiable bands when separated on the SDS-PAGE gel (MES buffer), with the intensified 25kDa and 85kDa protein bands serving as the two reference bands. Use molecular weight markers compatible with a western- imaging substrate, such as the Invitrogen iBright Prestained Protein Ladder or Invitrogen MagicMark XP Western Protein Standard, as a positive control. In a prestained protein ladder, each of these bands, or polypeptides, are already stained with a dye. Exposure Time: 30 seconds.The Unveil Unstained Protein Ladder is a mixture of 12 unstained recombinant proteins covering a wide range of molecular weights from 10 to 200 kDa. Secondary: Quanta BioDesign HRP-Goat anti-Rabbit IgG (H&L) (11-0201-0503) at a 1:100,000 dilution. Primary antibody: Proteintech Beta Catenin 51067-2-AP, 1:20,000. After transferring the protein bands onto the blot paper, stain the paper with Ponceau-S. In particular, our SignalBright has unparalleled performance to competitor products with highly sensitive detection, minimal optimization required, and long, stable signal duration.Ĭomparison of Proteintech’s SignalBright Pro (PK10011), SignalBright Plus (PK10012), and SignalBright Max (PK10013) Enhanced Chemiluminescent Substrate. If you want to do with unstained ladder yet, I recommend to do all steps of western blot just routinely do. Proteintech’s SignalBright Pro (PK10011), SignalBright Plus (PK10012), and SignalBright Max (PK10013) Enhanced Chemiluminescent Substrate have different levels of sensitivity and signal duration (see above table). ![]() We have three reagents available, enabling the detection of proteins low to high femtogram levels. We offer a blue prestained protein standard, as well as a colored prestained protein standard with multi-colored. Sizes range from 10 to 250 kDa which is ideal for accurate molecular weight determination for a wide range of expressed proteins. SignalBright Enhanced Chemiluminescent substrates - luminol-based, chemiluminescent substrate for HRP (horseradish peroxidase) which provides a much higher sensitivity over traditional ECL reagents. New England Biolabs offers a selection of highly pure protein standards. ![]()
