Check if the same lab product or an alternative is used in the 5 most similar protocols
Human umbilical vein endothelial cells (HUVEC) were purchased from Lonza and cultured in M199 medium (Corning) supplemented with 10% FBS, penicillin–streptomycin, endothelial cell growth factor from sheep brain extract, and 5 U/ml heparin on gelatin–coated dishes in a 37 °C incubator with 5% CO2. Passage 4 – passage 7 cells were used for experiments. Endothelial markers including VE-Cad, CD31, and ERG were used for cell characterization by immunofluorescence.
Detailed cell authentication information of HUVEC can be acquired from Lonza. In brief, routine characterization of HUVEC includes morphological observation throughout serial passages and all lots produced after 01 May 2010 stain at least 90% double-positive for endothelial cell markers CD31/CD105 and negative for alpha smooth muscle actin marker at passage 4. Pre-screened HUVEC are guaranteed to test positive for angiogenesis and vascular cell health markers, eNOS, Tie-2, VEGFr2, and Axl in the first passage out of cryopreservation (From Lonza).
Upon purchase, all cells are performance assayed and test negative for HIV-1, mycoplasma, hepatitis-B, hepatitis-C, bacteria, yeast and fungi. Cell performance and characterization are measured after recovery from cryopreservation.

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.
