High Molecular Weight Ladder

Low molecular weight range.

High molecular weight ladder.

6 5 200 kda. A high molecular weight ladder polymer based on 5 5 6 6 tetrahydroxy 3 3 3 3 tetramethylspirobisindane and 1 4 dicyanotetraflurobenzene has been synthesized by polycondensation under high intensity mixing conditions at about 155 c and cyclic free products were obtained in high yield with low molecular weight distribution 1 7 2 3. Bio rad protein ladders have been formulated and combined for use as molecular weight markers in a variety of applications including sds page ief 2 d page and western blotting. The ladder is a mixture of chromatography purified individual dna fragments.

Himark pre stained protein standard is designed for analysis of high molecular weight proteins and consists of nine protein bands ranging from 30 460 kda. Prestained protein ladders precision plus protein standards have the same gel migration patterns with three high intensity reference bands 25 50 and 75 kd and provide exceptional lot to lot molecular weight consistency. Protein dna and rna marker. High intensity prestained multicolored bands allow distinction of closely related proteins.

Compare and view all other protein standards and ladders. Therefore when used in gel electrophoresis markers effectively provide a logarithmic scale by which to estimate the size of the other fragments. Generuler high range dna ladder can be labeled radioactively with t4 polynucleotide kinase see protocol in the resources. These protein ladders for sds page are available in three size ranges.

Color coded prestained protein marker high range 43 315 kda is a mixture of purified proteins covalently coupled to blue green orange or pink dyes that resolves to 8 bands between 43 and 315 kda when electrophoresed. The protein standard is supplied in a ready to use format for direct loading onto gels. No need to heat reduce or add sample buffer prior to use. Each marker is quantitated to yield uniform band intensities when stained with coomassie brilliant blue r 250 following sds page.

More intense bands on gels and blots and have improved band spacing for more accurate molecular weight determination. Thermo scientific generuler high range dna ladder is recommended for fast sizing and approximate quantification of high molecular weight double stranded dna on agarose gels in 1 5 hour 0 4 agarose gel. A molecular weight size marker also referred to as a protein ladder dna ladder or rna ladder is a set of standards that are used to identify the approximate size of a molecule run on a gel during electrophoresis using the principle that molecular weight is inversely proportional to migration rate through a gel matrix. 44 3 200 kda and broad molecular weight range.

Neb also offers various conventional double stranded dna molecular weight markers with sizes up to 23 kb and markers for pulsed field gel electrophoresis pfge ranging from 1 5 to 1 018 kb. Protein molecular weight marker ladder. Neb dna ladders are available in standard formats and in a variety of convenient ready to load formats.
