CovaChem’s Molecular Biology Grade DMSO is highly purified and intended for use in biological, proteomics, and other sensitive assays. DMSO is a useful polar, aprotic solvent routinely used in protein chemistry and bioconjugation reactions. This anhydrous solvent, is ideal for dissolving protein crosslinkers and protein modifiers prior to addition to aqueous protein reactions, and is well suited for peptide synthesis. This product is conveniently packaged in 25 mL bottles to ensure fresh solvent is available for each application.

  • DCC (Dicyclohexylcarbodiimide)

    N,N''-Dicyclohexylcarbodiimide (DCC) is a zero length crosslinker. Dicyclohexylcarbodiimide is a coupling reagent used to couple carboxylic acids (COOH) to primary amines (-NH2).

  • DSP Crosslinker

    Lomant's reagent (DSP) is a reducible homobifunctional crosslinker. Another common name for this reagent is DTSP. DSP contains two NHS esters and contains a disulfide linkage that is cleavable.

  • EGS Crosslinker

    Ethylene glycol bis(succininic acid) N-hydroxysuccinimide ester) is a cleavable, homobifuntional crosslinker that contains two NHS functional groups. The NHS functional groups of EGS are selectively reactive towards primary amines at pH 7 to 9. EGS is cleavable with hydroxylamine at pH 8.5. EGS is often used as a cleavable option when disulfide containing crosslinkers, such as DSP (CovaChem 13304) and DTSSP (CovaChem 13303) are not an option due to the desire to retain disulfide networks of a protein intact.

  • GMBS Crosslinker

    4-Maleimidobutyric acid N-hydroxysuccinimide ester (GMBS) is a heterobifunctional crosslinker with a spacer length of 7.4 Å. BMPS contains an amine reactive, NHS ester, and a maleimide group which is reactive towards sulfhydryl functional groups.

  • LC-SPDP Crosslinker

    Succinimidyl 6-[3-(2-pyridyldithio)propionamido] hexanoate (LC-SPDP) is a heterobifunctional crosslinker that is amino reactive on one end and sulfhydryl reactive on the other end. LC-SPDP contains a long spacer arm (15.7 Å)for increased molecular flexibility and a reducible disulfide, which is allows for cleavage of the crosslinker after crosslink formation.
