Pigment epithelium-derived factor (PEDF) is a 47kDa secreted glycoprotein that belongs to the non-inhibitory serpin family group. PEDF is widely expressed in adult and fetal tissues, including brain, spinal cord, plasma, bone, prostate, pancreas, heart and lung. PEDF acts as an angiogenesis inhibitor with neurotrophic, immunomodulation and antitumor properties. It functions as anti-angiogenic agent by counterbalancing the proangiogenic effect of VEGF. PEDF is one of the most abundant proteins released by adipocytes and induces insulin resistance in adipocytes and human skeletal muscle cells. Recently, it has been reported that PEDF is sufficient to maintain the self-renewal of pluripotent human embryonic stem cells. Anti-PEDF (human), mAb (rec.) (Serpy-1-4) is an antibody developed by antibody phage display technology using a human naive antibody gene library. These libraries consist of scFv (single chain fragment variable) composed of VH (variable domain of the human immunoglobulin heavy chain) and VL (variable domain of the human immunoglobulin light chain) connected by a polypeptide linker. The antibody fragments are displayed on the surface of filamentous bacteriophage (M13). This scFv was selected by affinity selection on antigen in a process termed panning. Multiple rounds of panning are performed to enrich for antigen-specific scFv-phage. Monoclonal antibodies are subsequently identified by screening after each round of selection. The selected monoclonal scFv is cloned into an appropriate vector containing a Fc portion of interest and then produced in mammalian cells to generate an IgG like scFv-Fc fusion protein.

TRITON™ X-100 (Polyethylene glycol tert-octylphenyl ether)

Supplier: MP Biomedicals

Triton® X-100 is an alkylaryl polyether alcohol. It is a nonionic surfactant prepared by the reaction of octylphenol with ethylene oxide. The number ("-100") relates only indirectly to the number of ethylene oxide units in the structure.
Triton X-100 is a non-ionic surfactant and emulsifier which is often used in biochemical applications to solubilize proteins. Triton X-100 has no antimicrobial properties. It is considered as a comparatively mild detergent, non-denaturing, and is reported in numerous references as a routinely added reagent. It does absorb in the ultraviolet region of the spectrum, however, so can interfere with protein quantitation.
The principal uses of Triton® X-100 is in industrial and household detergent applications and in emulsifying agents. It is employed in almost every type of liquid, paste, and powdered cleaning compound, ranging from heavy-duty industrial products to gentle detergents for fine fabrics. It is also important ingredient of primary emulsifier mixtures used in the manufacture of emulsion polymers, stabilizers in latex polymers, and emulsifiers for agricultural emulsion concentrates, and wettable powders.
Widely used non-ionic surfactant for recovery of membrane components under mild non-denaturing conditions.
