[問題] paper上的問題?

[youchang (悠哉寶寶)]

A TF-1 cell proliferation assay was used to assess the bioactivity of GMCSF–

GFP.  GMCSF–GFP maintains nearly 80% of the bioactivity of commercially

produced GMCSF.  GMCSF–GFP bioactivity. Indicated concentrations of GMCSF–

GFP and a GMCSF standard were added to cultures of cytokine-dependent cell line

TF-1. Cell proliferation was measured by OD 490 nm.

使用OD 490 nm測定的GMCSF–GFP bioactivity.

問題在於nearly 80%,paper上是因GMCSF–GFP及GMCSF濃度越高,OD 490 nm測的數值也

越高,但老師要知道那80%是以什麼為基準的?



謝謝! 我一直認為那是吸光值給的數值0.8轉成百分比

但老師說一定有個基準,不可能無故轉換成百分比!!

本人愚昧阿!!(一個頭兩個大阿!!)
