1 kb DNA Ladder
#22228-001 250 μl
#22228-005 5 × 250 μl
OriBio™ 1kb DNA Ladder is recommended for sizing and approximate quantification of a wide range of linear double-stranded DNA fragments from 1 kb-10 kb. The ladder consists of 8 linear double-stranded DNA fragments, and is premixed with 1× DNA loading dye for direct loading on agarose gel. The 4 kb fragment has increased intensity to serve as a reference band. The approximate mass of DNA in each of the bands is provided (base on a 5 µl/lane load) for estimation of sample DNA mass.
