Description Recombinant Human Macrophage colony-stimulating factor 1(CSF1) expressed in Yeast
Specifications Uniprot ID: P09603; Host: Homo sapiens (Human); Expression system: Yeast; Expression region: 33-554aa; Sequence information: Full Length of Mature Protein; Tag: N-terminal 6xHis-tagged; Purity: Greater than 90% as determined by SDS-PAGE.
Storage_and_shipping Shipped on ice packs (+4°C). The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. Repeated freezing and thawing should be avoided. Store working aliquots at 4°C for up to one week.
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.
Additional description Colonies can be formed by stimulating factors or recombinant GM-CSF and CSFs activity expressed in Units compared to a standard.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.
