1000 Kb Ladder
The 500 and 1 000 base pair bands have increased intensity to serve as reference points.
1000 kb ladder. Small size suitable for 200 gel lanes. Supplied with free vial of gel loading dye purple 6x no sds. We recommend loading 0 5 μg of 1 kb dna ladder diluted in sample buffer. We offer conventional dna markers as well as a wide range of dna ladders ranging from 10 bp up to 48 5 kb.
Description invitrogen 1 kb plus dna ladder is designed for sizing and approximate quantification of double stranded dna in the range of 100 bp to 15 000 bp. The dna ladder consists of 14 dna fragments and is provided with 6x tritrack dna loading dye highlights of 1 kb dna ladde. We also offer markers suitable for use in pulsed field gel electrophoresis pfge extending up to 1000 kb. New england biolabs sells a wide range of double stranded dna molecular weight markers for electrophoresis.
This dna 1 kb ladder contains 11 fragments consisting of 500 bp repeats from 0 5 to 3 kb 1 kb repeats from 3 to 6 kb and 2 kb repeats from 6 to 10 kb. The approximate mass of dna in each of the bands is provided assuming a 0 5 μg load for approximating the mass of dna in comparably intense samples of similar size. All fragments have a 4 base 5 overhangs that can be end labeled using t4 polynucleotide kinase m0201 or filled in using dna polymerase i klenow fragment m0210 1. Goldbio s ready to use 1kb ladder serves as a clear dna standard with 13 band fragments and greater band intensity for reference at the 3kb and 1kb bands.
The 500 bp 1000 bp and 3000 bp fragment are used as reference band. Dna electrophoresis electrophoresis introduction to markers and ladders. Quick load purple 1 kb plus dna ladder. Easy to identify reference bands.
1 kb plus dna ladder consists of 18 individual chromatography purified dna fragments and has a reference band at 1 500 bp for easy orientation. The 1000 bp 1 kb dna ladder was designed for precise qualitative and approximately quantification of dna mass. Large size suitable for 1000 gel lanes.
