example 1
[0027]The silk was washed twice with deionized water and put into a drying box, dried at 55 °C for 1 hour, 200 g of silk was taken, added to 2 kg of 5% sodium carbonate solution, heated to 95 °C for 30 minutes, and centrifuged to obtain Precipitate and supernatant were washed twice with deionized water, and then the precipitate was repeatedly boiled for 3 times, and the supernatant was combined, and evaporated under reduced pressure to concentrate to 10% of the combined supernatant volume to obtain a concentrated solution, which was then concentrated. The solution was put into a dialysis bag with a molecular weight of 1000 for 6 days of dialysis, and deionized water was replaced every 4 hours. After the dialysis, the retentate was taken, and the retentate was placed in a freeze-drying box to freeze dry for 10 hours to obtain sericin, and 10 g of sericin was taken. Protein, 30g lauroyl chloride, add 300mL deionized water, stir at 300r / min for 20min, adjust pH to 8 with 5% sodium...
example 2
[0029] The silk was washed twice with deionized water and put into a drying oven, dried at 57 °C for 1 hour, 250 g of silk was taken, added to 2 kg of a 5% sodium carbonate solution, heated to 97 °C for cooking for 35 minutes, and centrifuged to obtain The precipitate and the supernatant were washed twice with deionized water, and the precipitate was repeatedly boiled for 4 times, then the supernatant was combined and evaporated under reduced pressure to 15% of the combined supernatant volume to obtain a concentrated solution. The solution was put into a dialysis bag with a molecular weight of 1250 for dialysis for 7 days, and deionized water was replaced every 6 hours. After the dialysis, the retentate was taken, and the retentate was placed in a freeze-drying box to freeze dry for 15 hours to obtain sericin, and 15g of sericin was taken. Protein, 40g of lauroyl chloride, added to 400mL of deionized water, stirred at 350r / min for 25min, then adjusted the pH to 8 with a mass fr...
example 3
[0031] The silk was washed three times with deionized water and put into a drying box, dried at 60 °C for 2 hours, 300 g of silk was taken, added to 3 kg of a 5% sodium carbonate solution, heated to 100 °C for 40 minutes, and centrifuged to obtain Precipitate and supernatant were washed three times with deionized water, and then the precipitate was repeatedly boiled for five times, and the supernatant was combined, and evaporated under reduced pressure to concentrate to 10-20% of the combined volume of the supernatant to obtain a concentrated solution. The concentrated solution was put into a dialysis bag with a molecular weight of 5000 for dialysis for 8 days, and deionized water was replaced every 8 hours. After the dialysis, the retentate was taken, and the retentate was placed in a freeze-drying box for lyophilization for 20 hours to obtain sericin. Take 20g Sericin, 50g lauroyl chloride, add 500mL deionized water, stir at 400r / min for 30min, adjust pH to 9 with 5% sodium h...
