Enrichment of functional mitochondria. Mitochondria were prepared from various mouse tissues using the Mitochondria Isolation Kit, mouse tissue. The mitochondria preparations from muscle, liver, and brain, as well as the flow-through fractions were analyzed by a coupled enzymatic citrate synthase assay.
The data indicate that citrate synthase activity, normalized to the activity per mg protein assayed in the flow-through fraction, is highly enriched in the eluate.

Isolation of high-purity mitochondria from mouse liver. After isolation of mitochondria from mouse liver using the Mitochondria Isolation Kit, mouse tissue, equal amounts of mitochondrial protein lysates were analyzed by Western blotting against TOM20. PEX1, a cytoplasmic protein anchored to peroxisomal membranes, served as a control.
The results show an effective enrichment of mitochondria and no contamination of the mitochondria fraction by peroxisomes.

Specifications for Mitochondria Isolation Kit, mouse tissue

Overview

The Mitochondria Isolation Kit, mouse tissue facilitates the isolation of functional and viable mitochondria from mouse tissue. The isolation protocol is based on the renowned MACS Technology, which enables fast isolation of high purity and high yield mitochondria.

Detailed product information

The Mitochondria MidiMACS Starting Kit, mouse tissue includes:
  • 1 Mitochondria Isolation Kit, mouse tissue
  • 1 MidiMACS Separator
  • 1 MACS MultiStand
The Mitochondria QuadroMACS Starting Kit, mouse tissue includes:
  • 1 Mitochondria Isolation Kit, mouse tissue
  • 1 QuadroMACS Separator
  • 1 MACS MultiStand

Detailed procedure

Tissues can be homogenized with the gentleMACS or gentleMACS Octo Dissociator in combination with the Mitochondria Extraction Kit – Tissue. After one-step homogenization of the tissue and lysis of the cell suspension, mitochondria are magnetically labeled with Anti-TOM22 MicroBeads, mouse, which bind to the translocase of the outer mitochondrial membrane 22 protein (TOM22). The sample is loaded onto an LS Column placed in a MidiMACS or QuadroMACS Separator. After washing, only the magnetically labeled mitochondria are retained on the column. The column is removed from the separator and functional mouse mitochondria are eluted from the column.

Downstream applications

After isolation mitochondria can be further subjected to Western blot analysis
