Early endosomes (EE) provide the starting point for late endosome maturation. The EEs are mainly derived from primary endocytic vesicles that fuse with each other. EEs receive endocytic cargos not only through the clathrin-mediated pathway but several other pathways. In addition to their roles in normal cell physiology, endocytic processes play a key role in many diseases such as Alzheimer’s disease and inherited lysosomal storage diseases. Traditional methods for isolating endosomes are based on density gradient ultracentrifugation. The protocol requires large amount of starting material and the methods are tedious and time consuming.

101Bio Endosome Isolation Kit provides a spin-column based novel endosome isolation technology which is rapid and simple. It only requires smaller amount of cultured cells or milligram amounts of tissues. This kit can precipitate and significantly enrich early endosomes from cultured cells or tissues. The availability of the kit should facilitate the research in the field.

  • Read the entire procedures carefully. Chill protein extraction filter cartridge with collection tube on ice prior to use.
  • All centrifugation steps should be performed at 4oC in a cold room or in a refrigerated microfuge.
  • To study protein phosphorylation, phosphatase inhibitors (such as PhosStop from Roche) should be added to Buffer A prior to use. The use of protease inhibitor cocktails is optional.
  • It is recommended to use BCA Protein Assay Kit for determination of protein concentration.
  • This protocol is developed and validated by 101Bio’s OEM partner. Spin column based protein extraction and cell fractionation technologies were developed by 101Bio’s OEM partner.
