The GPC analysis was performed at Toray Research Center (Tokyo, Japan). The purified sample (1 mg) was dissolved in 1 mL of dimethyl formamide (DMF) containing 50 mM lithium chloride (LiCl), and 200 μL of the sample was subjected to GPC. The molecular mass was estimated using a high-performance liquid chromatograph equipped with a refractive index detector (RI-8020; TOSOH, Tokyo, Japan), and TSK gel α-4000 and TSK gel α-2500 columns (7.8 mm × 30 cm; TOSOH, Tokyo, Japan), which were connected directly. DMF containing 50 mM LiCl was used as the solvent at a flow rate of 0.7 mL/min and the column temperature was maintained at 23 °C. The eluted sample was used for molecular mass determination, with a calibration curve obtained using standard polystyrene kits (PSt Quick E and F; TOSOH, Tokyo, Japan).
Pst quick e and f
Manufactured by Tosoh
Sourced in Japan
The PSt Quick E and F are laboratory equipment designed for the analysis of various substances. They are used for the measurement of partial pressure of oxygen (pO2) and partial pressure of carbon dioxide (pCO2) in samples. The PSt Quick E and F provide accurate and reliable results for these parameters.

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.
