Activated M-PVA Magnetic Beads

M-PVA Ak1x NHS-activated beads

Standard particle sizes:

M-PVA Ak11: 0.5 - 1 µm (article No. 221)

M-PVA Ak12: 1 - 3 µm (article No. 222)

Min. quantity delivered:

2 ml bead suspension

Concentration: Magnetite:

50 - 60 %

Activation degree:

M-PVA Ak11 390 µmol NHS/g
M-PVA Ak12 350 µmol NHS/g

Binding capacity:

M-PVA Ak11 8 - 20 mg protein/g
M-PVA Ak12 5 - 15 mg protein/g

Storage:

in isopropanol

Stability:

at least 1 month at 4 °C

Properties: These superparamagnetic beads consist of a matrix of carboxylated polyvinyl alcohol, which is subsequently activated with N-hydroxysuccinimidyl (NHS) ester functionalities and can therefore be used for the direct coupling of proteins, nucleic acids or other ligands with amino functionalities.

M-PVA Ak2x NCO-activated beads

Standard particle sizes:

M-PVA Ak21: 0.5 - 1 µm (article No. 224)

M-PVA Ak22: 1 - 3 µm (article No. 225)

Min. quantity delivered:

2 ml bead suspension

Concentration:

25 mg/ml

Magnetite:

50 - 60 %

Activation degree:

M-PVA Ak21 250 µmol NCO/g
M-PVA Ak22 220 µmol NCO/g

Storage:

in dimethylformamide (DMF)

Stability:

at least 1 month at 4 °C

Properties: These superparamagnetic beads consist of a matrix of polyvinyl alcohol, which is subsequently activated by the introduction of isocyanate funcionalities via an eightatom spacer. M-PVA Ak2x can therefore be used for the direct coupling of molecules containing amino or hydroxy functionalities.
