Phosphate → HCID 20485290, compound

Participants

Reaction Steps

To a solution of BSA (300 mg, 5×10-4 mmole) in 20 ml of phosphate buffer was added the hapten, 2,2-dipropylglutaric anhydride as prepared in Example 5 (55 mg, 0.25 mmole in 200 ml THF) in 4 μl portions over an hour. The resulting clear solution was stirred at 4° overnight, after which it was dialyzed in 7×2 liter of water adjusted to pH8 with phosphate buffer, followed by one time with deionized water. The dialysis took 5 days. Lyophilization gave 320 mg of conjugate having a hapten number of 40 as estimated by the amino group precipitation method.
