Recombinant Xenopus laevis Vitellogenin-B2

Product Type Recombinant Protein
Uniprot No. P19011
Species Xenopus laevis (African clawed frog)
Protein Names Recommended name: Vitellogenin-B2 Short name= VTG B2
Storage 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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Function Precursor of the major egg-yolk proteins that are sources of nutrients during early development of oviparous organisms.
Tissue Specificity Produced by the liver, secreted into the blood and then sequestered by receptor mediated endocytosis into growing oocytes, where it is generally cleaved, giving rise to the respective yolk components.
