THREE RESIN REACTORS IN SERIES PEPTIDE SYNTHESIZER
A Solid Phase Peptide Synthesis (SPPS) device and method of using the same for manufacturing peptides is taught herein. The system comprises at least two reactors, each reactor including a quantity of SPPS resin. The reactors are positioned in series. A de-protecting agent is added to the first reactor and then transferred to the second and third reactors, in series, thereby operating to de-protect the protected N-group. Wash solvent is added to the first reactor and then transferred to the second and this operation repeated several times. Likewise, an amino acid activated ester solution is added, in series, to the first, second and third reactors, thereby operating to couple the amino acid to the de-protected N-group. Wash solvent is added to the first reactor and then transferred to the second and this operation repeated several times prior to the next cycle. The use of the reactors in series reduces the overall solvent required. Online LCMS is also used to monitor progress and identity of reactions happening within the solid phase resin particles.
Unit for treatment of a bioprocess liquid
The invention discloses a first unit (1) for treatment of a bioprocess liquid comprising a first lateral face (2), a second lateral face (3) and a front face (4) which meets the two said lateral faces. The front face comprises: a plurality of valves (7) adapted to receive and act upon one or more legs (8) of a disposable flow path (6); optionally one or more pumps (10) adapted to receive and act upon one or more legs of the disposable flow path; optionally one or more sensors (11) adapted to receive and to measure one or more parameters in one or more legs of the disposable flow path; wherein the plurality of valves and optional pumps and sensors are vertically offset from each other to give one or more legs of a disposable flow path received by said valves and optional pumps and sensors a slope of at least 3.0 degrees from the horizontal plane (h).

Separation method
The invention relates to a method of isolating an immunoglobulin, comprising the steps of: a) providing a separation matrix comprising multimers of immunoglobulin-binding alkali-stabilized Protein A domains covalently coupled to a porous support, b) contacting a liquid sample comprising an immunoglobulin with the separation matrix, c) washing said separation matrix with a washing liquid, d) eluting the immunoglobulin from the separation matrix with an elution liquid, and e) cleaning the separation matrix with a cleaning liquid,
wherein the alkali-stabilized Protein A domains comprise mutants of a parental Fc-binding domain of Staphylococcus Protein A (SpA), as defined by SEQ ID NO: 51 or SEQ ID NO: 52, wherein the amino acid residues at positions 13 and 44 of SEQ ID NO: 51 or 52 are asparagines and wherein at least the asparagine residue at position 3 of SEQ ID NO: 51 or 52 has been mutated to an amino acid selected from the group consisting of glutamic acid, lysine, tyrosine, threonine, phenylalanine, leucine, isoleucine, tryptophan, methionine, valine, alanine, histidine and arginine.
SELECTING CHROMATOGRAPHY PARAMETERS FOR MANUFACTURING THERAPEUTIC PROTEINS
In a method for facilitating selection of chromatography parameters for manufacturing a therapeutic protein, one or more process parameter values associated with a hypothetical chromatography process, and one or more molecular descriptors descriptive of the therapeutic protein, are received. The method also includes predicting a performance indicator for the hypothetical chromatography process at least by analyzing the one or more process parameters and the one or more molecular descriptors using a machine learning model. The machine learning model is a regression tree model, an extreme gradient boost model, or an elastic net model. The method also includes causing the predicted performance indicator, and/or an indication of whether the predicted performance indicator satisfies one or more acceptability criteria, to be presented to a user via a user interface.
DECOLORIZATION AND PURIFICATION METHOD OF BHET MATERIAL
The disclosure provides a decolorization and purification method of BHET material, which includes the following steps. A first dose of activated carbon is added to preliminarily treat the BHET material. After the preliminary treatment, a first cooling crystallization process and filtration are performed to obtain BHET crystals. Afterwards, an oxidant is used to chemically react with the BHET crystals to destroy a dye or impurities, and then a second dose of activated carbon is added to adsorb a chemically reacted oxide. Next, a second cooling crystallization process, filtration, and drying are performed to obtain a finished product of BHET.

Process for production of essentially pure delta-9-tetrahydrocannabinol
The present invention describes a method which outlines a process for conversion of CBD to a Δ.sup.9-tetrahydrocannabinol (Δ.sup.9-THC) compound or derivative thereof involving treating a naturally produced CBD intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the Δ.sup.9-tetrahydrocannabinol compound or derivative thereof at a relatively high concentration. The source of the CBD is from industrial hemp having less than 0.3% Δ.sup.9-THC and extracting and purifying a CBD distillate or isolate or a combination thereof. This procedure will produce Δ.sup.9-THC that is essentially free from any other cannabinoids other than some trace amounts of the initial CBD starting material, or about 95% Δ.sup.9-THC and 2-4% CBD. Another aspect of the present invention relates to a process for further purification and enrichment of the Δ.sup.9-THC using distillation and collecting an essentially pure fraction of Δ.sup.9-THC using additional distillation or enrichment form of purification. Included are methods and processes to scale the reaction from the lab to large scale manufacturing. Included are methods for adding a molecule marker to authenticate high purity Δ.sup.9-THC products. Formulations and uses for pharmaceuticals, nutraceuticals, food products, and topicals are also provided.
Automated fluid handling system
Automated fluid handling system comprising a housing and two or more fluid handling units arranged as interchangeable modular components with an external fluidics section and an internal non fluidics section, and wherein the housing comprises a liquid handling panel with two or more of component positions for receiving said interchangeable modular components such that the external fluidics section is separated from the non fluidics section by the liquid handling panel.
CONTROL OF WET SCRUBBER OXIDATION INHIBITOR AND BYPRODUCT RECOVERY
