Please help with identifying this font from AminoLab Analysis Report

[jp06]

I stumbled upon this example report PDF online and just came to love the font used for the table. I just can't find the exact font for this even after using tools online. I think one distinctive bit is the `g`, if that helps. I'd just put here the PDF and a sample image. If it's ever commercial, I hope you can suggest some similar free alternatives too (so far, I've taken a liking to Average Sans and Merriweather Sans). Thanks in advance!
