Appearance: White to off-white solid Solubility: Soluble in Water and Methanol pH value of 5%(wt/wt) water solution: 5.00-7.00 Melting Point: 110.0℃-114.0℃ Purity: 98.00%min by HPLC Specific Optical Rotation: -34°~-29° Identification by IR: complies to standard UV Absorption: Abs. @ 300 nm, 0.13max Abs. @ 400 nm, 0.06max Application: IPTG [367-93-1] is an extremely potent inducer that is not metabolized by bacteria and is very stable, and is therefore widely used in laboratories for cloning experiments that require induction of beta-galactosidase activity. It is often used in combination with X-Gal or Bluo-Gal for blue-white screening of recombinant bacterial colonies that induce expression of the lac manipulator in E. coli. IPTG binds to the lacI blocker protein and alters its conformation to prevent inhibition of the beta-galactosidase coding gene lacZ

Currently under developpment are test kits for: - Legionella pneumophila SG 1-15 - Pseudomonas aeruginosa

Alpha Lifetech Inc.'s custom chicken polyclonal antibody (pAbs) services including the full-service from chicken immunization, serum-collection, titer analysis, antibody production to antibody modification. IgY is the main serum immunoglobulin in chicken. Same as IgG, IgY contains two heavy and two light polypeptide chains, shaped in the Y characteristics and presents two binding sites for the antigen. But there is only a little or no immunological cross-reactivity between IgY and mammalian IgG. IgY has a relative higher molecular weight (~180kDa and ~160kDa to IgG) due to an extra constant domain in its heavy chain (H), lacks a well-defined hinge region and has an unique oligosaccharide. Alpha Lifetech Inc. can provide a complete service including antigen synthesis, modification, chicken immunization and IgY purification to produce polyclonal antibody (pAbs) in chickens.

Alpha Lifetech Inc. has a comprehensive R&D platform with unsurpassed technical expertise, by which we can offer our customers the full range of mouse hybridoma development services, including antigen design, animal immunization and hybridoma characteristics, to meet their requirements for each project.
