General description

To view protocols from Sigma collaborators for ExpressMag system visit the link below.


When coupled with MISSION® ExpressMag® magnetics, ExpressMag beads will increase the transduction efficiency of lentiviral particles. Increases in transduction efficiency are particularly striking in primary cells and in suspension cells.

Preparation Note

Do NOT FREEZE! Significant decrease in efficacy will occur if ExpressMag bead solution is frozen.

Product Information Sheet

Quotes and Ordering

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.

  2. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  3. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  4. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

  6. What MISSION products have been successfully introduced into cells using ExpressMag® beads?

    MISSION Lentiviral Particles (various targets/clones), SHC002V, SHC003V and SHC008V have been successfully introduced into cells using ExpressMag beads.

  7. What is the typical fold increase in transduction efficiency when using ExpressMag beads?

    The transduction efficiency increase observed when using the ExpressMag products will depend on the cell line. It is reasonable to expect a roughly 10-fold or greater increase.

  8. What cell lines have been transduced successfully using ExpressMag Beads?

    The following cell types have been successfully transduced using ExpressMag Beads: PBL, PBMC, T Cells, GMB primary tumor cells, A549, NYGM, T98G, U251, U87,YH-13, YK6-1, KS-1, NIH3T3, K562, Vero, HeLa, CHO, L929, B95a, H9, HUVEC, CD4+ Primary Human T-Cells, Human Bone Marrow Macrophages, Primary Keratinocytes, SKOV3, MM-AN, MEF and CD 34+.

  9. What other viruses have been successfully introduced into cells via the use of ExpressMag beads?

    Adenovirus, SIV, Retrovirus, Measles virus and HIV have all been successfully introduced into cells using ExpressMag.
