A beginners guide to Sf9 and Sf21 insect cell line culture and troubleshooting.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Recombinant proteins are not only a crucial research tool but are also widely implemented in biomedicine. There are a number of expression systems used for recombinant protein production. Among them Spodoptera frugiperda (Sf) insect cell system is a powerful tool for multiprotein expression. Most commonly used are Sf9 and Sf21 cell lines due to their cost-effectiveness and availability. While a collection of protocols describing the Sf cell lines culturing is available, we have found them incomplete and their adaptation to real laboratory conditions challenging. Here we created a user-friendly hands-on protocol suitable for beginners. Our work combines the efforts of three independent laboratories which culture Sf cells, two labs with long experience, and one which recently successfully set up this system from scratch. We propose novel tricks and tips that allow for culturing of healthy Sf cells, and high protein yield production. Besides catering for beginners, our protocol can serve as a troubleshooting guide for more experienced researchers. We believe that this work is useful for biochemistry all the way to biomedical laboratories. Starting with an exhaustive description of Sf cell lines, through baculovirus expression vector system characteristic, this publication is a protocol, troubleshooting guide and compendium in one.
