基本信息
General description【一般描述】 | Fragment mixture prepared by cleavage of pBR322 DNA with restriction endonuclease Hae III. Size Range: 8 to 587 bp |
Application【应用】 | DNA Molecular Weight Marker V is used for the size determination of DNA in agarose gels. It simplifies accurate molecular weight determination of double-stranded DNA fragments generated by: <UL><LI>Restriction digests</LI> <LI>PCR</LI> <LI>RT-PCR</LI></UL> |
Components【组分】 | Ready-to-use solution, 250μg/ml, in TE buffer (10mM Tris-HCl, 1mM EDTA, pH 8.0) |
Sequence【序列】 | The mixture contains 22 DNA fragments with the following base pair lengths (1 base pair = 660 daltons): 8, 11, 18, 21, 51, 57, 64, 80, 89, 104, 123, 124, 184, 192, 213, 234, 267, 434, 458, 504, 540, and 587 as determined by computer analysis of the pBR322 sequence. 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. |
Unit Definition【单位定义】 | 50 μg = 1A260 unit |
Preparation Note【制备说明】 | Activator: Ammonia, pyridine, imidazole, all at pH >7; detergents Working concentration: A suggested working ratio, for immediate use in coupling procedures, is 2 mg POD to 4 mg lgG (molar ratio = 2:1, POD:IgG). Storage conditions (working solution): 2 to 8 ℃ Once thawed we recommend further storage at 2 to 8 ℃. |
Other Notes【其他说明】 | 仅用于生命科学研究。不可用于诊断。 |
