Check if the same lab product or an alternative is used in the 5 most similar protocols
After the experiment (14 days) desirable tissues from glyphosate-treated and control plants were collected. Then tissues were washed in saline solution (0.75%), homogenized in 0.2 M pH 7.4 phosphate buffer (2 mL) and centrifuged (8000 rpm) at 4°C for 25 minutes. The supernatants were kept in Teflon tubes and stored at -80°C to perform the biochemical analysis of carbohydrate and total protein. Leaves were separated and put in acetone (80%, Sisco Research Laboratories) for the analysis of chlorophyll, i.e., chlorophyll a (Chlo-a), chlorophyll b (Chlo-b) and total chlorophyll (Chlo-t) [18 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
