Fractionation of Methyl Cellulose Hydrolysate.

Thyroglobulin fractionation on diethylaminoethyl cellulose columns.

Thyroglobulin may be defined as the iodine-containing protein of the thyroid gland which has a sedimentation coefficient of 4o.w = 19 S, an electrophoretic mobility at pH 8.6 of approximately 5 x 10F5 cm2 volt-l set-1, and a steep salting out curve at about 38% ammonium sulfate saturation at neutral pH (1). Although other iodoproteins, both soluble in neutral salt and attached to cell particles...

Cryopreservation of rooster sperm using methyl cellulose.

Experiments were designed to determine when, during the cryopreservation process, sperm lose fertilizing capacity and whether the cryoprotectant, methyl cellulose (MC), could be used in combination with glycerol to cryopreserve sperm and remain in the inseminate without reducing fertility. Semen diluted in Minnesota Avian extender (MNA) and inseminated immediately had greater fertility (75%) th...

Fractionation of cornstalk into cellulose and lignin for the production of sodium carboxymethyl cellulose

This thesis project aimed to fractionate cornstalk into cellulose and lignin, and utilize the crude cornstalk-derived cellulose for the production of sodium carboxymethyl cellulose and the lignin for the sybthesis of bio-based phenol-formaldehyde resole resins as wood adhesives. In this thesis work, cornstalk was efficiently fractionated into crude cellulose and crude lignin in mixed solvents o...

Electrophoretic fractionation of serum glycoproteins on cellulose acetate.

In a procedure for the routine electrophoretic fractionation of serum glycoproteinson cellulose acetate, electrophoretic fractionation is followed by staining utilizing the periodicacid-Schiff reaction. The patterns are scannedwith a recording densitometer and simultaneouslyquantitated with an attached integrator. For 100 healthy blood donors,the meansand standarddeviationswere: albumin, 10.9±1...
