DNA Molecular Weight Marker IV

产品说明

一般描述

Fragment mixture prepared by cleavage of equimolar amounts of λDNA and pSPTBM20 DNA with restriction endonucleases Sty I and Sau I.
Ready-to-use solution, 250 μg/ml, in TE buffer (10 mM Tris-HCl, 1 mM EDTA, pH 8.0).

Size Range: 0.07 to 19.3 kbp

应用

DNA Molecular Weight Marker IV is used for the size determination of DNA in agarose gels. It simplifies accurate molecular weight determination of double-stranded DNA fragments generated by:

• Restriction digests
• PCR
• RT-PCR

序列

The mixture contains 14 DNA fragments with the following base pair lengths (1 base pair = 660 daltons): 74, 421, 697, 925, 1150, 1489, 1882, 2322, 2690, 3140, 4254, 5526, 7743, and 19329 as determined by computer analysis of λDNA and pSPTBM 20 sequences.
Note: Fragment lengths are derived from computer analysis of the DNA sequence. Depending on the size range of the marker, the smallest fragments will only be visible on overloaded gels.
