Specifications

MagDetect™ WCX beads are magnetic silica beads coated with a weak cation exchange surface (WCX). The beads are intended for:
-Sample preparation and pre-fractionation prior to mass spectrometry (e.g. MALDI-TOF analysis) and HPLC
-Protein and peptide separation for multiple downstream applications, e.g. enzymatic assays
-Detergent removal
-Fractionation of clinical samples e.g. serum, plasma, tissues, CSF, urine and cell lysate
-Enrichment of phosphorylated proteins and peptides
Catalog #	M2106-70
	Peptides and proteins bind cationic groups on the surface of MagDetect-WAX, while impurities are washed away. After elution in desorption buffer, purified peptides and proteins are ready for downstream use.
Storage and Stability	May be stored at 4°C. For long-term storage, store at 4°C. Do not freeze! Store beads in well closed vial and in upright position to prevent drying of the beads since this makes them more difficult to resuspend and may decrease their activity. Vortex bead suspension well before use. Beads are stable for at least 6 months.
Purity	Highly Purified
Concentration	~10mg/ml
Form	Supplied as a suspension in ddH2O..
