Check if the same lab product or an alternative is used in the 5 most similar protocols
Tris-egg yolk extender was prepared freshly by mixing 1.363 g Tris-aminomethane (Merck, CAS Number: 108382, Darmstadt, Germany), 0.762 g citric acid (CAS Number: 77-92-9 100241-Merck Millipore), 1.5 g lactose monohydrate (Merck CAS Number: 1.07660), and 2.7 g D-(+)-raffinose pentahydrate (Merck, CAS Number: 512-69-6), 0.5 g D(-)-fructose (Merck, CAS Number: 57-48-7 104007) was dissolved in 80 mL double-distilled water and homogenized with a magnetic stirrer for 10-15 min [8 (link)]. The extender osmolarity was 295 mOsm/L (WESCOR model 5500, INC, USA). The solution was heated to 100°C for a few minutes and cooled to room temperature (26°C), after which it was mixed with 0.1 g penicillin G (Meiji Seika Co., Tokyo, Japan) and 0.1 streptomycin sulfate (Meiji). The mixture was homogenized again for 10-15 min. Egg yolk (20 mL) was dissolved in 80 mL of the mixture, centrifuged 492 × g for 15 min, the supernatant was used as an extender while the precipitate was removed [2 (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.
