  Supplied as a sterile-filtered, lyophilized powder in 0.0045mM NaHCO3.
• Storage_stability
  Lyophilized powder may be stored at 4 degree C for short-term only. Reconstitute to nominal volume by adding sterile 0.4% NaHCO3 and store at -20 degree C. Reconstituted product is stable for 12 months at -20 degree C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
• Description
  The antagonist receptor ligand binding will be in contrast with agonist activity. MyBioSource produces more antagonist and receptor related products as 1. Aplha, transcription related growth factors and stimulating factors or repressing nuclear factors are complex subunits of proteins involved in cell differentiation. Complex subunit associated factors are involved in hybridoma growth, Eosinohils, eritroid proliferation and derived from promotor binding stimulating subunits on the DNA binding complex. NFKB 105 subunit for example is a polypetide gene enhancer of genes in B cells.
• Properties
  Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.
• Gene
  Human or mouse Leptin (from Greek λεπτός leptos, "thin") the "satiety hormone", is a hormone made by adipose cells that helps to regulate energy balance by inhibiting hunger. Leptin is opposed by the actions of the hormone ghrelin, the "hunger hormone". Both hormones act on receptors in the arcuate nucleus of the hypothalamus to regulate appetite to achieve energy homeostasis. ELISA kits and peptides and antibodies are available.
