"Protein molecular weight markers"

Supplier: VWR Chemicals

Protein Marker II for accurate molecular weight determination of proteins by SDS-PAGE.

Supplier: Cytiva

For determination of molecular weight of uncharacterised protein samples with precision by comparison with carefully selected standards.

Supplier: Cytiva

Rainbow™ molecular weight markers enable faster and simpler identification of proteins on SDS polyacrylamide gels. These ready to load markers provide sharper, more intense bands on gels and blots, and have improved band spacing for more accurate molecular weight determination. The bright, distinctive colours of the markers allow easier confirmation of transfer to blotting membranes and orientation.

Supplier: EDVOTEK

Using prestained LyphoProteins, subunit molecular weights are determined by analysis using denaturing SDS vertical polyacrylamide gel electrophoresis. Prestained proteins with unknown molecular weights are assigned molecular weights based on the relative mobility of prestained standard protein markers.

Supplier: MP Biomedicals

Actin is a purified protein from Rabbit muscle, for use as a high molecular weight marker or as a standard.

Supplier: Cytiva

Amersham™ ECL™ Plex™ fluorescent Rainbow™ markers are protein molecular weight markers optimised for use with the ECL™ Plex™ Western blotting detection system. They are designed to provide visible marker bands on gels and membranes, as well as fluorescent images using Cy3 and Cy5 channels.

Supplier: Merck

Blue dextran are used in affinity chromatography, gel filtration chromatography, protein chromatography and molecular weight markers.

peqGOLD pre-stained protein marker IV is a mixture of 10 recombinant, highly purified coloured proteins supplied 'ready to use' in loading buffer. The protein concentrations are optimised to yield well-defined bands directly visible in SDS-polyacrylamide gels.

Supplier: Abcam

Native human PF4 protein is a human full length platelet factor 4 protein, in the 32 to 101 aa range with >95% purity and suitable for SDS-PAGE. The predicted molecular weight of ab81754 native protein is 7,8 kDa. Save time and ensure accurate results use our PF4 protein Heparin-neutralizing activity verified by clotting assay. Marker of platelet activation. Optimal protein bioactivity and stability.

Supplier: VWR Chemicals

peqGOLD pre-stained Protein Marker VI is a mixture of 10 coloured proteins. These proteins are recombinantly produced in E.coli, highly purified and supplied 'ready to use' in loading buffer. The protein concentrations are optimised to yield well-defined bands directly visible in SDS polyacrylamide gels.

Supplier: VWR Chemicals

peqGOLD Protein Marker I is a mixture of seven purified proteins which are re-dissolved 'ready to use' in loading buffer. The proteins resolve into sharp, tight bands in the range of 14,4 to 116,0 kDa when analysed by SDS-PAGE and stained with Coomassie Brilliant Blue R-250.

Supplier: Abcam

Unstained Protein Ladder ab234618 contains 12 unstained recombinant proteins covering a wide range of molecular weights from 10-200 kDa.

Supplier: Molecular Devices

The ScanLater™ Western blot protein ladder is a mixture of seven biotinylated recombinant proteins at 10, 20, 40, 60, 80, 100, and 140 kD.

Supplier: G-Biosciences

Ready-to-screen, human, single tissue blots, from both normal and tumour tissues. G-Biosciences pre-made blots are prepared with the appropriate GenLysate™ and 50 μg protein is loaded onto a 4 to 20% denaturing polyacrylamide gel, along with a prestained molecular weight marker. After the proteins are resolved, they are transferred to a PVDF membrane, using our Western transfer buffer.
