2/19/2024 0 Comments Protein ladder for western blot![]() proteins of interest, and evaluate western transfer efficiency. Protein Ladders and Standards (Markers) Recombinant Protein Standards (Markers) Western Blotting Protein Standards. Protein Molecular Weight Marker “wide Range” (prestained) is ideal for precise sizing of proteins by SDS-PAGE and for Western blotting. Tricolor Broad Range Prestained Protein Ladder contains 13 proteins that. Protein Marker “wide Range” 6,5 kD to 270 kD 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. Under suggested conditions, GENE’s Protein Ladder resolves 10 major bands in 4-12% Bis-Tris Gel (MES buffer) and after Western blotting to the nitrocellulose membrane. The Bullseye Pre-stained Protein Ladder contains 10 prestained proteins, covering a wide range of molecular weights from 10 to 180kDa. – 2.5 μl per well for general Western transferring.Ħ2.5 mM Tris-H 3PO 4 (pH 7.5 at 25 ☌), 1 mM EDTA, 2% SDS, 10 mM DTT, 1 mM NaN 3, 33% glycerol. – 3 μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively. mPAGE ® Western Protein Standards consist of seven recombinant proteins at 20 kDa, 30 kDa, 40 kDa, 50 kDa, 60 kDa, 80 kDa and 120 kDa with an IgG binding site that binds to most antibodies. The ladder is supplied in the gel loading buffer and is ready to use. ScanLaterTM Western Blot Protein Ladder Reagent. The BlueRAY Prestained Protein Ladder is designed for monitoring protein separated during SDS-PAGE, verification of Western transfer efficiency on membranes (. The 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. Proteins are covalently coupled with a blue chromophore except for three reference bands (two orange bands at 30 kDa and 270 kDa and one green band at 52 kDa) when separated on SDS-PAGE (Tris-glycine buffer). GangNam-Stain Prestained Protein Ladder is very suitable for protein separation from SDS-PAGE, confirmation of Western blot transfer efficiency, CBB staining. ![]() Additional data should be considered for a more accurate adjustment.Ġ.2~0.4 mg/ml of each band of protein is stored in a mixture of solution that contains: 20 mM Trisphosphate at pH 7.5, 2% SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15% (v/v) Glycerol.ĥμl of IRIS9 Prestained Protein Ladder (PM009) resolves 9 bands in 4-20% SDS-PAGE (Tris-glycine buffer) and after Western blotting to PVDF membrane.This Protein Ladder is a three-color protein standard with 10 pre-stained proteins covering a wide range of molecular weights from 6.5 to 270 kDa. Note: The molecular weight of each protein (kDa) was measured against an unstained protein ladder in every electrophoresis condition. 2.5 μl per well for general Western transferring. Add Tween 20 detergent to the wash buffer to a final concentration of 0.05. Increase the number of washes and/or the volume of buffer used. Refer to the IRIS9 Prestained Protein Ladder patterns in various electrophoresis conditions:ģ μl or 5 μl per loading for clear visualization during electrophoresis on 15-well or 10-well mini-gel, respectively. MagicMark XP Western Protein Standardis specifically designed for easy and convenient protein molecular weight estimation directly on western blots. Use Thermo Scientific SuperSignal Western Blot Enhancer to reduce background and enhance detection of low-abundance and weakly immunoreactive antigens. ![]() Guide for Molecular Weight Estimation (kDa) The IRIS9 Prestained Protein Ladder keeps track of the size and separation of proteins during SDS-polyacrylamide gel electrophoresis, approximating the target protein size and validating the Western transfer efficiency on PVDF, nylon, or nitrocellulose membranes. The 9 recombinant proteins are covalently coupled with blue chromophore, while 2 red bands at 70 kDa and 30 kDa, a green band at 15 kDa and a newly designed peacock green band at 60 kDa serve as reference bands. The IRIS9 Prestained Protein Ladder is a combination of 9 pre-stained proteins with molecular weights from 15 to 180 kDa. ![]()
