Negative magnetic streptavidin microbead selection

Manufactured by Miltenyi Biotec

Negative magnetic streptavidin microbead selection is a lab equipment product that allows for the isolation of target cells or molecules by negatively selecting for unwanted cells or molecules. The product utilizes magnetic microbeads coated with streptavidin to bind and remove unwanted components from a sample, leaving the desired target for further analysis or processing.

Detecting DNA Strand Breaks in cDCs

Check if the same lab product or an alternative is used in the 5 most similar protocols
The APO-BrdU TUNEL kit (BD) was used to detect DNA strand breaks. cDCs were prepared as described above prior to enrichment by negative magnetic streptavidin microbead selection (Miltenyi) to exclude T cells (CD3ε), B cells (B220), and NK cells (CD49b) (biotinylated antibodies from BioLegend). Cells were then stained for cell surface markers as described above prior to TUNEL analysis according to the manufacturer’s protocol.

Enrichment and Isolation of Naive CD4+ T Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Spleens and peripheral lymph nodes of OT-II Foxp3RFP donor mice were pooled together and enriched by depletion. CD4+ T cells were enriched by negative magnetic streptavidin microbead selection (Miltenyi), which excluded cells expressing the surface molecules CD8α, B220, CD11b, CD11c, and CD49b (biotinylated antibodies from BioLegend). Enriched Foxp3(RFP)neg CD25neg cells were sorted on FACSAria Fusion or FACSAriaIII (BD) instruments. After sorting, cells were washed twice in PBS and counted. 3–5 million cells were injected intravenously into the tail vein of each recipient mouse.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
