Thanks...But I am not sure that;s trustable or not...we have been using the Amax for ys, and it works nicely...however, it is pretty expensive and I am debating whether I shall switch to Neon for my future lab...THus, I would love to see some first-hand experience...
So what types of cells are you folks working on and how efficient it is? Cost? thanks in advance...debating which one I shall order for my future lab ...I have been using Amax for ys but it could get too expensive...

It turns out that our lab use for AMO transformation into all kinds of mammalian cell lines. It works much better than lipid-based methods. Not sure about other types of oligos. Sorry.

I c, anyone in your group used for plasmids? BTW, small fragments are much easier to get in...In fact, Fugene HD is very good for those too. literally 100%...lipofectamine sucks...all those transfected with siRNA died in my hands...
I tried primary mouse B and T cells, ~50% transfection efficiency for plasmid DNA and ~100% for small RNA. I never used Amaxa, but according to someone who used it, Neon is much more adjustable and controllable.

yeah, Amax lacks flexibilities, all you can do is to following the protocols ...but some say it has better efficiency..but if you can get 50% for B and T cells, I would say that's very good...what about the survival rate? Amax survival rate is horrible...although the efficiency is very good for our cells...BTW, how much the reagents cost?

I have not used Neon for a while, but I think 50% survival rate would be reasonable to expect. Of course you'll need to optimize the voltage, duration time, and number of pulses. Our neighbor lab and I changed the tips and buffers ten times less frequently than suggested by Invitrogen and it still works well. I guess the company is counting on the consumables for hefty profits. Also we requested a lot more (free) buffers at the time we purchased the machine. The main advantage for electroporation transfection would mainly be small RNA delivery. For large piece of DNA, I still prefer retroviruse-based method, which is stable transfer and I don't need to worry about the viability issue.

17k is huge...so have u folks tried something like 5-10k range? I have lots around that...Amax can do pretty well with 5-10K range...but the survival rate is low...
BTW, for small RNA, we have great experience with Fugene HD...it is just so easy and great...

there's another serials electroporators by Nepagene of Japan Very good in vivo performance. seems also good for in vitro Check that.

我对此有类似的问题,就是那些特别大的质粒,大家都是怎么转进去的? 我们有一个14k 的荧光蛋白的质粒,用一般的方法转完之后都必须sorting 一次才能看到30%的荧光细胞。特别麻烦。本来想做一个stable line 的, 可是因为是plasmid 的integration 就不高,根本筛不出来。 而fusion protein construct >10kbp,貌似不太好装到病毒里面去。 我们用的是MEF, 更是一个特别麻烦的细胞,以前用过的Bio-rad 的机器, 一点都不好似,还不如我用lipofectamine Plus 的效率高。

No, that won't work, at least in theory. You may insert the piggybac sequence into your vector then -- should not be hard. Or you may try more transferring conditions
Anyone has experience with MV4-11 AML cell line? Amaxa p-max ctrl plasmid work great (4k), but all my coding plasmid (~9 to 10k) can not even get in. I want to adjust the program but don't know which one to adjust to.
