Title: Follistatin and method of purifying same.
Inventor: LING NICHOLAS CHAI-KWAN
IPC: A61K38/04
Filed: 1988-08-26
Abstract: Two follistatin proteins with inhibin-like activity were isolated from porcine follicular fluid using heparin-Sepharose affinity chromatography, followed by gel filtration on Sephacryl S-200 and then six steps of high-performance liquid chromatography. Each isolated molecule is a monomer having a molecular weight of at least about 32,000 daltons. Microsequencing revealed the NH2-terminal portions both to be Gly-Asn-Cys-Trp-Leu-Arg-Gln-Ala-Lys-Asn-Gly-Arg-Cys-Gln-Val-Leu. The larger protein has 315 residues and is believed to be glycosylated. The smaller protein is a 288-residue, C-terminally shortened version thereof. These proteins specifically inhibit basal secretion of FSH, but not of LH, in a rat anterior pituitary monolayer culture system. The Half-maximal effective dose for both is 2.5-6.0 ng/ml. Human and rat follistatins exhibit very high homology with the porcine protein, with the human differing from porcine in only 4 residues out of 315 and with the rat differing from porcine in only 8 residues out of 315.

Abstract: A compensation circuit 2 for sensor lag provides a modified sensor temperature signal for subsequent use in controlling the sensed temperature. The compensation circuit 2 digitally compares a current sensor temperature representative signal and a sensor temperature signal at a last or preceeding sample time to produce a difference signal which is converted to a sensor slope signal 16 and is multiplied by a sensor time constant 18. The resulting signal is passed through a filter 20 to eliminate transient effects and is summed with the original sensor temperature signal to provide a sensed temperature signal for control of the temperature whereby the sensed temperature is a better estimate of the actual environmental temperature controlled by a thermostat utilizing the sensed temperature signal.
