biotin-dpeg(4)-nhs

Alpha Biopharma offers a broad product line of biochemicals and reagents for basic researc and drug discovery. We are a professional biochemical company engaged in researching, developing, manufacturing pharmaceutical peptide、new amino acid 、peptide synthetic technique and new type of peptide. Moreover, we are focused on nucleic acid and other small organic compounds. Alpha Biopharma company not only provides contract research but custom synthesis service.
After years of concentrated research and development, we have made a great breakthrough in peptide synthesis. Most of our scientists come from national famous universities and research institutes. Most of them have more than 5 years of experience in small molecule drug synthesis, which makes it easier for them to understand various principles, difficulties and solutions in peptide synthesis process. Alabiochem has innovated and mastered advanced technologies such as special amino acids, special protective amino acids, peptide fragments, new functional materials for peptide synthesis, and peptide coupling. This leads to a significant reduction in the cost of peptide synthesis compared to other peptide synthesis companies. We have not only successfully solved or reduced the technical difficulties of peptide β folding, coupling racemization, poor solubility, aspartimide, etc., but also made use of our own invention process, and are good at the preparation of long peptide and difficult peptide.

IRIS Biotech is specialized in reagents for Peptide Synthesis, PEGylation, Life Science Research and Biocatalysis. We have specific know-how and production capabilities to manufacture and supply products from the following areas from Grams to Multi-Ton Lots:

• Starting Materials for Peptide Synthesis, Peptidomimetic and Medicinal Chemistry
  Protected Amino Acids, Coupling Reagents, Linkers and Resins, Natural and Unusual Amino Acids and Building Blocks used in Peptide Synthesis, Peptidomimetic and Medicinal Chemistry.
  
  
• Reagents for PEGylation
  Monodisperse and polydisperse hydrophilic linkers, used to improve solubility and pharmacokinetic properties of peptides, proteins, biopharmaceuticals and organic drug molecules. We carry the world wide largest portfolio, as we supply short monodisperse compounds with increasing chain length up to large, polydisperse polymers.
  
  
• Reagents for Life Science Research
  Enzyme Substrates and Special Proteins, Dyes, Diagnostic and Biochemistry Tools
  Natural Products, with biological and pharmacological activity, like immunsuppressiva: Aflatoxines, Cyclosporines, Geldanamycin, Rapamycin, etc.)
  Carbohydrates (Derivatives of Arabinose, Galactose, Glucose, Xylose, etc.)
  
  
• Biocatalysis
  We offer a wide range of unusual and innovative enzymes, immobilised enzymes and enzyme carriers for modern biocatalysis. Synthesis or optical resolution of racemic mixtures of Amines, Amides and Esters are applications, which are wide used. Esterification and transesterification with lipases and esterases are used in commercial productions from food industry to biodiesel production.
  
  
• Contract Manufacturing
  We are carrying out many Contract Manufacturing projects in these areas (cGMP and ISO9000); our strong points are unusual derivatives with one or several chiral centres.

SiChem synthesizes APIs for early stage (Toxicology) drug design. A special field of expertise is the preparation of biologically and pharmacologically active compounds with increased bioavailibity (prodrugs).

SiChem has previously developed unique and efficient preparative synthesis techniques in the area of enantioseparation to prepare larger amounts up to the 100 g scale.
For quality control and metabolic studies high-tech analytical equipment, namely HPLC-MS and NMR, is available.
The diagnostics under development will be suitable for high-throughput screening i.e. in pharmaceutical industry.

To complete complex projects for our clients from the pharmaceutical sector requires concentration, flexibility, innovation and sometimes also creativity on our part every day. Our extensive experience in the area of custom synthesis/contract research helps us finding optimum solutions for new tasks as well.

We assist you competently until the agreed objectives are met, keeping in dialogue with you and responding to your instructions and requests. And we provide professional documentation as a matter of course.

We make our chemical and technical know-how available to you for custom synthesis tasks and innovative research. This will enable you to concentrate on your core business and even save you expenditure for additional infrastructure and personnel.

We support you in the area of classical custom synthesis (building blocks and target structures) for the areas of medical research, pharmaceutical development, lead compound and prodrug development. If more specialist tasks are involved, such as metabolite synthesis (synthetic or enzymatic) or the synthesis of various salts of a substance and their crystallisation behaviour (polymorphism screening via X-ray), we are also the people to turn to.

We will also take on your separation problems: we can handle the separation of racemates of up to 1 kg. Of course we will also purify your compounds (by chromatography or crystallisation) and, if you wish, even get them ready for distribution (package, label, box etc.). We support you from A to Z or only in small partial areas, tailoring our activities to your individual needs.
