Figure 3From: Human saliva, plasma and breast milk exosomes contain RNA: uptake by macrophagesCharacterisation of breast milk exosomes by Western blot. The exosomal proteins from breast milk exosomes were loaded onto a 10% acrylamide gel and transferred to a nitrocellulose membrane. The breast milk exosomes are positive for Hsc70 and CD81, but negative for the endoplasmic reticulum protein, calnexin. Macrophage protein ("Cells") was used as positive control.Back to article page
