Lipids are a family of organic compounds that include monoglycerides, diglycerides, triglycerides, etc. The presence of the lipids in the biological sample is usually poorly compatible with many downstream applications, including ELISA, protease digestion of proteins, isoelectric focusing, and mass spectrometry (MS). To enable downstream analysis, it is critical to remove the lipids from the biological sample such as ascites, serum, cell & tissue culture, bile, and organ homogenates. For such purposes, traditionally, chloroform or column has been the preferred method for Delipidation. However, using the solvent removal agent or spin column to remove the lipids is tedious, timing-consuming, suffering from sample losses, environmental concerns, and challenging to adapt to high-throughput automation. We develop a novel, super-efficient lipid-specific removal agent based on magnetic beads to overcome these limitations.
BcMag™ One-Step Lipids Removal Kit uses specially designed magnetic beads to efficiently bind and remove lipids from ascites, serum, cell & tissue culture, bile, and organ homogenates. The convenient single-step, one-tube purification protocol takes only 2 minutes with very little hands-on time. The beads enable 96 samples to be processed simultaneously in less than 10 minutes.
1.
Add the beads to a sample solution.
2.
Mix the beads with the sample by vortex or pipetting.
3.
Magnetically remove the beads.
4.
Aspirate the supernatant containing a lipid-free sample.

The following protocol is an example. The beads and sample volume can be rational Scale-up (or down). Do not use buffers containing organic solvents.
Procedure
1.
Shake the bottle to resuspend the magnetic beads until it is homogeneous entirely.
2.
Add 10μl magnetic beads to a 100 μl sample containing lipids.
3.
Mix the sample with beads for 1-2 minutes by slowly pipetting up and down 20-25 times or vortex for 5 minutes at 2000 rpm for PCR plates or 800 rpm for Elisa plates.
4.
Place the sample plate or tube on the magnetic separation plate for 30 seconds or until the solution is clear.
5.
Transfer the supernatant to a clean plate/tube while the sample plate remains on the magnetic separation plate. The sample is ready for downstream applications.
