MagSi-STA

Streptavidin beads for Immunoassays

Magnetic particles are used as a solid support phase in immunoassays. MagSi-STA are superparamagnetic silica beads with a surface coating of streptavidin for use with biotinylated antibodies.

MagSi-STA Trial kit

The MagSi-STA Trial kit offers the opportunity of screening many types of streptavidin beads simultaneously. The kit is especially useful when required specifications for magnetic beads are unknown.

This kit includes 1 ml of each of the the 8 different MagSi-STA products (MagSi-STA 600, MagSi-STA 600 BI, MagSi-STA 1.0, MagSi-STA 1.0 L, MagSi-STA 1.0 TL, MagSi-STA 1.0 TS, MagSi-STA 3.0 L and MagSi-STA 3.0 TL) and is intended for evaluation purposes during trial phase of developing new assays, or bead replacement in existing assays.

MagSi-STA Streptavidin Beads

The MagSi-STA Trial kit is also an excellent tool for feedback on a customized bead-type, which would fit any immunoassay in an optimal manner. Contact us during and after your trials to discuss the customized options.

* Type refers to the applied streptavidin coupling chemistry.

C (Carboxyl): This type is intended for applications which require a relatively hydrophilic surface and also includes a spacer.
T (Tosyl): This type is intended for applications which require beads which are more hydrophobic.
