Check if the same lab product or an alternative is used in the 5 most similar protocols
Human umbilical vein endothelial cells (HUVECs) were purchased from Lonza (Lonza,
Breda, The Netherlands) and maintained in EGM-2 media consisting of endothelial
basal medium-2 supplemented with growth factors and antibiotics (EGM-2
SingleQuots kit, Lonza, The Netherlands). The effect of hyperglycemia on HUVECs
was investigated by incubating cells in EGM-2 media with 30 mM D-glucose. The
normal EGM-2 media used as a control contained 5.5 mM D-glucose. In all
experiments, cells from passage 4 or 5 were used and cultured at 37°C in a 5%
CO2/95% humidified atmosphere.

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.
