4ARM-PEG-COOHFour arm polyethylene glycol carboxyl group

Purity:95%above

CAS：—

Status: Solid

Solubility: soluble inDMSO DMFMost organic solvents have good water solubility.

Usage: For scientific research only, not for diagnosis and treatment. Polyethylene glycol carboxyl groups easily form amide bonds with amino groups and undergo condensation reactions with hydroxyl groups.

Usage: Freeze storage, slowly thaw before use, fill with nitrogen after use

Storage: Freeze at -20 ° C, can be divided to avoid repeated freeze-thaw cycles, ready to use, do not store in solution form.
