Antibody drugs are a kind of drugs that treat diseases through artificially synthesized antibodies, achieving therapeutic purposes by specifically binding with target molecules. Common types of antibody drugs include monoclonal antibodies, artificially synthesized antibody fragments, immunotoxins, antibody-drug conjugates, etc. Antibody drugs have shown remarkable therapeutic effects in the ...
These vaccines can effectively stimulate the immune system to respond to specific pathogens, thereby providing protective effects. ...
Gas chromatography (GC) systems are widely used for analyzing chemical compounds, with accurate machine calibration being vital to their performance. ...
Accurate calibration in gas chromatography transforms good measurements into precise, actionable data. When handling high-stakes tasks in environmental science or pharmaceuticals, ensuring calibration at parts per billion (ppb) becomes non-negotiable. This article will show you how ppb-level calibration standards sharpen gas chromatography’s capabilities and why they matter in your ...
Plant growth regulators (PGR) are a class of small molecule compounds with plant hormone activity that can affect plant growth and development. Such compounds are often used to enhance plant resistance, promote plant cell division and growth, increase yield, and improve quality. There are many types of growth regulators with different properties. However, as a chemical substance, plant growth ...
Antibody drugs, as a type of therapeutic biological preparation, require not only precise bioengineering techniques for their production but also rely on a variety of raw materials and ancillary materials to support the production and stability of the drugs. These materials include but are not limited to amino acids, sugars, protein stabilizers, buffers, surfactants, etc. They play an ...
So far, metaproteomics research has covered various environmental samples, including fermented food, biofilms of acidic mine wastewater, wastewater, marine samples, soil systems, permafrost, human microbiomes, and various environmental ecology and gut flora. ...
Peptides are a class of compounds whose molecular structure lies between amino acids and proteins, composed of 20 natural amino acids in different compositions and arrangements, from dipeptides to complex linear or cyclic structures of polypeptides. We refer to peptides composed of 2-10 amino acids as oligopeptides, those composed of 11-50 amino acids as polypeptides, and those composed of more ...
Peptide identification is a core process in proteomics, involving the analysis of proteins in biological samples to identify specific peptide segments. This process is not only crucial for basic biological research, but it also plays a key role in disease diagnosis, drug discovery, and biomarker identification. A complete peptide identification process can be approximately divided into the ...
These particles become a series of zones, each particle in its own density zone. Chromatography 1. Gel filtration chromatography Gel filtration chromatography separates substances by molecular size. ...
In biological experiments, protein sequencing is a critical technique that enables the determination of the amino acid sequence of proteins, thereby revealing their function and structure. However, a common question arises: is it possible to sequence impure proteins? This paper will explore this issue.Importance of Protein PurityFirstly, let's understand why protein sequencing requires high ...
Oligonucleotides are typically composed of short-chain nucleotides (deoxyribonucleotides or ribonucleotides) of less than 20, serving as short RNA and DNA oligomers. They can be used as probes to determine the structure of DNA or RNA, and are used in processes such as gene chips, electrophoresis, and fluorescence in situ hybridization.Oligonucleotides are widely used in biology, agriculture, ...
Messenger RNA (mRNA) is a ribonucleotide sequence that encodes a protein, primarily consisting of five main parts: the 5' end is a cap structure (Cap), the 5' untranslated region (UTR) related to translation efficiency, the open reading frame (ORF) area that encodes a protein, the 3' UTR related to translation efficiency, and the polyA tail synthesized by multiple adenosine monophosphates, which ...
Proteins are the main carriers of life activities, and whether proteins are expressed and the amount of expression are closely related to the physiological status and health of organisms. The type, structure, quantity, and modification status of proteins directly affect various functions of organisms. In order to deeply understand the structure and function of proteins, proteomics technology was ...
Peptides refer to a class of compounds with molecular structures between amino acids and proteins, which are composed of 20 natural amino acids in different ways. They are the general term for peptides from dipeptides to complex linear or cyclic structures. We call peptides composed of 2-10 amino acids oligopeptides, also known as small molecule peptides, with an average molecular weight of amino ...
