Nuts can be planted with husks, but are easier to handle and sort for

Place nuts in a bucket of water to soften and then peel the husks by hand.
After removing husks, rinse nuts in water. Discard nuts that float; nuts
that sink have full kernels and are more likely to germinate.
Walnut seeds require stratification (cold treatment) before they will

个人建议哈。这个Amaxa最好还是先做个test。找个GFP plasmid,用他们提供的那个也
可以,然后买个test kit,里面有两个还是三个不同的buffers,然后按照他们的

efficiency。flow的时候可以加上PI,这样可以了解viability。
这样可以选个比较好的protocol。
