136 results about "Glycin" patented technology

Glycin, or N-(4-hydroxyphenyl)glycine, is N-substituted p-aminophenol. It is a photographic developing agent used in classic black-and-white developer solutions. It is unrelated to the amino acid glycine. It is typically characterized as thin plates of white or silvery powder, although aged samples appear brown. It is sparingly soluble in water and most organic solvents; it is readily soluble in alkalies and acids.

Catalyst for preparing carbon nanotube and its prepn

The catalyst for preparing carbon nanotube has perovskite or perovskite-like structure. Under heating condition, the catalyst is reduced with hydrogen to produce hydroxide of RE or alkali earth element. During its preparation, salt or oxide of corresponding element is used as main material, and one or several of citric acid, tartaric acid, glycin and EDTA is used as complexing agent and burning agent to prepare the catalyst via gel burning synthesis process in water or ethanol solution. If necessary, ammonia or ammonium compound as pore creating agent may be added in the preparation process to increase the specific surface area of the catalyst. The catalyst makes the prepared carbon nanotube possess even homogeneous tube diameter and even high yield.

Preparation process of intravenous injection human immunoglobulin

The invention relates to a preparation process of intravenous injection human immunoglobulin, belonging to the field of pharmaceuticals. On a basis of a traditional preparation process of intravenous injection human immunoglobulin with the low protein concentration of 5 percent, a filter pressing method is adopted instead of a centrifuging method in an extraction process. During hyperfiltration, the protein concentration is adjusted to 3-6 percent, a pH value is adjusted to 6.4-6.6 with 0.5 mol/L of NaOH; then, 1 mol/L phosphoric acid-NaOH buffer solution is added to adjust the electrical conductivity which is measured to be 0.175-0.205 s/m at a temperature T of 19 DEG C; and a chromatography method is adopted to carrying out column chromatography and purification by using upper ion exchange columns after the electrical conductivity is adjusted. The protein impurities can be effectively removed, the protein purify and the product yield are improved; maltose or glycin is used as a protector, which benefits the improvement of the stability of the intravenous injection human immunoglobulin; and the glycin is used as the protector, which satisfies the clinical use of diabetics. According to the invention, the intravenous injection human immunoglobulin with the protein concentration of 5-11 percent can be obtained.

Monoclonal antibodies to progastrin

The present invention provides progastrin-binding molecules specific for progastrin that do not bind gastrin-17(G17), gastrin-34(G34), glycine-extended gastrin-17(G17-Gly), or glycine-extended gastrin-34(G34-Gly). Further, the invention provides monoclonal antibodies (MAbs) selective for sequences at the N-terminus and the C-terminus of the gastrin precursor molecule, progastrin and the hybridomas that produce these MAbs. Also provided are panels of Mabs useful for the detection and quantitation of progastrin and gastrin hormone species in immuno-detection and quantitation assays. These assays are useful for diagnosing and monitoring a gastrin-promoted disease or condition, or for monitoring the progress of a course of therapy. The invention further provides solid phase assays including immunohistochemical (IHC) and immunofluorescence (IF) assays suitable for detection and visualization of gastrin species in solid samples, such as biopsy samples or tissue slices. The progastrin-binding molecules are useful therapeutically for passive immunization against progastrin in progastrin-promoted diseases or conditions. Also provided are surrogate reference standard (SRS) molecules that are peptide chains of from about 10 to about 35 amino acids, wherein the SRS molecule comprises at least two epitopes found in a protein of interest of greater than about 50 amino acids. Such SRS molecules are useful as standards in place of authentic proteins of interest.
