Introduction to SoluLinK Bioconjugation Technology

SoluLinK’s core technology is based on the formation of a stable bis‐arylhydrazone formed from an aromatic hydrazine and an aromatic aldehyde.  S‐HyNic 1 (succinimidyl 6‐hydrazinonicotinate acetone hydrazone, SANH) is used to incorporate aromatic hydrazine moieties on biomolecules.  S‐HyNic is an amino‐reactive reagent that directly converts amino groups on biomolecules and surfaces to HyNic groups.  S‐ 4FB 2 (succinimidyl 4‐formylbenzoate, SFB) is used to convert amino groups to aromatic aldehydes (4‐formylbenzamide (4FB) groups).   Addition of a HyNic‐modified biomolecule to a 4FB‐modified biomolecule or surface directly leads to the formation of the conjugate (Figure 1).  The bis‐arylhydrazone bond is stable to 92O C and pH 2.0‐10.0.    The recommended pH for antibody conjugation is 6.0.    Unlike thiol‐based conjugation protocols where reducing reagents are required that that can compromise the activity of proteins by cleaving disulfide bonds, the HyNic‐4FB conjugation couple leaves disulfide bonds intact. No oxidants, reductants or metals are required in the preparation of conjugate.    Further enhancing the many advantages of the HyNic/4FB conjugation couple is the discovery by Dirksen et al.1 that showed that aniline catalyzes the formation of this Schiff’s base.    This is especially effective for large biomolecule conjugations.    In the case of antibody‐protein conjugations the addition of 10 mM aniline to the reaction mixture converts >95% of the antibody to conjugate in ~2 hours using 1‐2 mole equivalents of second protein. The HyNic‐4FB conjugation couple is chromophoric‐  the conjugate bond absorbs at 354 nm and has a molar extinction coefficient of 29000.    This allows (1) real time spectrophotometric monitoring of a conjugate reaction, (2) ability to ‘visualize’ the conjugate during chromatographic purification using a UV or photodiode array detector and (3) quantification of conjugation.  Furthermore, the level of incorporation of HyNic groups can be quantified colorimetrically as reaction with 2‐ sulfobenzaldehyde (SoluLinK catalog# # S‐2005‐100) yields a chromophoric product that absorbs at A350 with a molar extinction coefficient of 20000 (Figure 2).  Links to procedures and calculators to guide users through this process are given in the procedures below.   S‐HyNic (Solulink catalog: S‐1004‐105 (5 X 1.0 mg) and S‐1004‐010 (25 mg)) is an NHS ester that converts amines on biomolecules and surfaces to HyNic moieties for conjugation to 4FB‐modified biomolecules.
