DETACHaBEAD™ CD19 Kit

Dynabeads magnetic beads coated with antibody/ligand may be stored at 2-8 degrees C without loss of antigen binding capacity. For long-term storage, a final concentration of 0.02% NaN3 may be added to the antibody-coupled beads in a physiological buffer. Please note that not all coupled antibodies retain their function in long term storage. Verify your coupled antibody stability by testing in small scale. After storage, coated Dynabeads magnetic beads should be washed once in PBS/BSA for 5 min before use.

Both bead-to-target cell ratio and the concentration of beads in the bead/cell mixture are important and should be considered. For example, when using the Dynabeads magnetic beads M-450 CD4 positive isolation or depletion kit, a 4:1 bead-to-target cell ratio should be maintained. To capture 95% of target cells for molecular applications, the bead concentration must always be 1 x 10e7 beads per milliliter of sample. To deplete 99% CD4 cells from the starting sample, the bead concentration must always be 2 x 10e7 beads per milliliter of sample. Please consult the package insert for recommended bead concentrations of each product.

No, the data are not ideal when cells have beads attached to them. You need to use one of the Dynabeads Assays that allow you to remove the beads from your cells for downstream analysis. These include the Dynabeads FlowComp assays and DETACHaBEAD assays.

Bead-free cells can be isolated using Dynabeads kits that include DETACHaBEAD technology. These include the Dynabeads FlowComp kits and Dynabeads CELLection Cell Isolation Kits. Also, any of the negative isolation kits will generate cells that are bead-free.

This depends on the bead size. In general, for M-450 Dynabeads, 1 mg/mL beads is approximately equivalent to 1.3 X 10E7 beads/mL; for M-280 Dynabeads, 1 mg/mL beads is approximately equivalent to 6.7 X 10E7 beads/mL.
