Ing liver tissue was removed by suction. The egg sediment was suspended in 1.7 saline and transferred into 50 mL Falcon tubes and centrifuged at 1200 rpm for 5 min as well as the supernatant containing residual liver tissue was removed very carefully by suction. The egg pellet was suspended in 1.7 saline as well as the eggs have been separated from residual liver tissue by centrifugation more than Percoll gradient (Lewis 1998). The eggs have been recovered inside the pellet fraction and washed 4with 1.7 saline and stored frozen as a wet pellet at -20 . Ascaris suum was a kind present from Dr. Irma van Die, VU Medical Center, Amsterdam, Netherlands. Cell culture and desialylation HL-60 and Jurkat cells had been grown in RPMI supplemented with 2 mM L-glutamine and ten FBS at 37 in five CO2 atmosphere to 80 confluence density. The cells were harvested at their highest density following log-phase growth and washed 4with cold PBS and processed quickly or stored at -80 . For desialylation, HL-60 and Jurkat cells have been grown to 80 confluent density in RPMI as described above and washed 5with Hanks buffer. About 1 107 cells had been incubated with 15 mU of neuraminidase in 1 mL of Hanks buffer at 37 for 30 min. The cells had been washed 4with Hanks buffer and used for evaluation. As controls, HL-60 and Jurkat cells had been also mock treated by incubation in Hanks buffer without neuraminidase.M Mandalasi et al.Preparation of extracts To prepare SEA, S. mansoni eggs have been suspended in PBS supplemented with 5protease inhibitor cocktail (Roche, Indianapolis, IN) and sonicated on ice making use of a Branson sonifier (Branson Ultrasonic Corp.Linperlisib site , Danbury, CT).Dehydroaripiprazole Epigenetic Reader Domain The homogenate was centrifuged at 16,000 g for 30 min at 4 along with the supernatant fraction was recovered as SEA.PMID:23667820 The pellet fraction was suspended in PBS containing 5protease inhibitor cocktail and resuspended by sonication on ice. Triton X-100 was added to a final concentration of 0.5 and the homogenate was kept on ice for 30 min to solubilize membrane proteins. The homogenate was centrifuged at 16,000 g for 30 min at 4 and the supernatant fraction was recovered as detergent extracted egg antigen. The protein content material in the egg extracts had been determined by BCA assay and the extracts were aliquoted and stored at -20 . To prepare adult S. mansoni extracts, the adult worms were sonicated in PBS supplemented with 5protease inhibitor cocktail similar to that as described for SEA extract above. Triton X-100 was subsequently added to the homogenate to a final concentration of 0.five detergent plus the mixture was incubated on ice for 30 min. The homogenate was centrifuged at 16,000 g for 30 min at four and also the supernatant fraction was recovered as adult schistosome extract. The protein content material from the extract was determined by BCA assay and the samples were aliquoted and retailers at -20 . To prepare extracts of HL-60 and Jurkat cells, 1 108 HL-60 or Jurkat cells were suspended in 1 mL PBS supplemented with 1protease inhibitor cocktail and sonicated as described above. Triton X-100 was added for the homogenates to a final concentration of 0.two Triton X-100 and kept on ice for 30 min to solubilize proteins. The homogenates have been centrifuged at 16,000 g at 4 for 30 min to pellet insoluble components. The supernatant fractions were recovered as cell extracts as well as the protein contents have been determined by BCA protein assay. Enzyme-linked immunosorbent assay Microtiter wells have been coated with 50 L/well of either five g/ mL of SEA or 5 g/mL of neoglycoconjugates in PBS and blocked.
