Non CD4+ T cells are depleted by incubating your sample with the biotin antibody cocktail followed by incubation with magnetic Streptavidin Nanobeads. The magnetically labeled fraction is retained by the use of a magnetic separator. The untouched CD4+ T cells are collected by decanting the liquid in a clean tube. These are your cells of interest; do not discard the liquid. Some of the downstream applications include functional assays, gene expression, phenotypic characterization, etc.

MojoSort™ reagents are also compatible with column-based cell separation systems available from other vendors. Optimized protocols for cell separation using columns from in-house testing are provided for each kit under the “Related Protocols” section, as well as representative data on the product webpage (where available). Data generated using column separators are indicated on the figure legend.

Due to the property of the beads, MojoSort™ reagents typically require dilution for optimal use on column separators. Where available, recommended dilution factors for each kit component based on in-house testing are provided under the “Application Notes” section of the webpage.

Related FAQs

Is there a way to detach your magnetic particles from the cell surface?

No, not currently.  We have found that cells are functional without the need to detach the magnetic Nanobeads.

What is the size of your magnetic particles?

The average diameter is approximately 130 nm.

Are MojoSort™ Nanobeads compatible with other commercially available magnetic separation systems?

MojoSort™ magnetic particles can be used with other commercially available magnetic separators, both free standing magnets and column-based systems.  Because MojoSort™ protocols are optimized for the MojoSort™ separator, the protocols may need to be adjusted for other systems.  Please contact BioLegend Technical Service for more information and guidance. We do not recommend using MojoSort™ particles for BD’s IMag™ or Life Technologies’ DynaMag™.

What antibodies are present in the depletion cocktails provided for isolation kits?
