Alternative to Qiagen Puregene Tissue kit for HMW gDNA?

[dacotahm]

Hello,

We're extracting high molecular weight gDNA for PacBio from an insect-a bee- using the Qiagen Puregene Tissue kit (4g). We have trouble with this kit back-ordered all the time. Could someone from the community recommend an alternative for HMW gDNA that works well on tissue for PacBio?

Thanks,

Dacotah

I have tried the following protocol with insects and it works quite well in terms of purity and length:

Modified low‐salt CTAB extraction of high‐quality DNA from contaminant‐rich tissues

A benchtop protocol is available in the "Supporting Information" section.

Hi Dacotah,

Qiagen's PureGene kits are nearly identical to the former Epicentre MasterPue DNA Purification kits, which are now available through Lucigen/Biosearch Technologies. Catalog numbers would be MC85200 for 200 reactions and MC89010 for 10 reactions. Both are non-column based products.

Oh, that's great, thank you very much.
