Yes. Thanks, Vijay. Gosh, if that was the first one, I'm curious how many questions you got. But let me try. So a few things. You had it right. So the synthesis business, up 8% is, we think, a really healthy look for us, 2 consecutive quarters of increase from where we've been. I think you recall, we'd had a downward trend. And I think we had issues to resolve from a delivery standpoint. So we feel we're in a good position there.
We -- just to put some color on that, we've seen a lot of aggressive price pressure in the synthesis business that we did not chase down. And we had some delivery issues as we've been -- as we communicated to people, but we've resolved those. We continue to deliver extremely high quality, high speed. And we do really complicated things for customers. So we're really confident about that. The China business in synthesis has also been pretty healthy.
On the NGS business, the 13% growth is -- so I'll give you a couple of pieces there. One is just strong across-the-board capability. And Vijay, also every once in a while, we win a project that allows us to have a good slug of NGS business in a particular quarter, followed by digestion from that same customer until they come back for another study. But we had a good solid growth period in NGS, and we continue to be healthy there. We're making investments on new tools, continue to be aggressive about winning customer business. And we anticipate that will -- the investments that we make will allow us to continue to grow that business over the long term.
The Sanger business was flat. So just to give you an idea, so Sanger was 0. So when you put -- when you do the arithmetic there, indeed, Sanger was flat. One of the things I will say is as we announced the Plasmid-EZ capability where we do the measurement of the plasmid in the NGS business, and that was formerly some Sanger. So same customers, but the measurements that we're doing now, they don't -- we don't put those into the Sanger business per se. We put some of those into the NGS business.
It was relatively small. So it's not a big swinger here. But when -- in the past, when you've seen the Sanger business grow 3% and 4% year-over-year for us to have 0 there, we put a little bit of that -- what would have been otherwise Sanger growth into the NGS business. And then Vijay, if you remind me the next question?
