Carrier vs carrier- protein free? When would/wouldn’t I want a carrier protein?

Adding a carrier protein increases protein stability, extends shelf life, allows the protein to be stored at more dilute concentrations, and helps avoid the product sticking to the walls of the vial. Consequently, adding carrier proteins can be very helpful. However, most carrier proteins are animal-derived so for animal-free and sensitive applications and assays [...]

How to store growth factors

Growth factor shelf life is influenced by many factors, including storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally speaking, growth factors are most stable when lyophilized.  Our lyophilized proteins have been verified to be stable at room temperature for 3 days, or frozen for up to 2 years (either [...]

Stability of lyophilized proteins at room temperature

We have compared our lyophilized proteins incubated at 37 °C for 3 days with those stored at -80 °C and found no difference in their bioactivity (EC50) using our standard assays. Therefore, as part of our commitment to the environment and supporting more eco-friendly packaging, we send all of our lyophilized proteins at room [...]
