Acrp30 Human, HEK
Adiponectin Human Recombinant, HEK

Synonyms:
Acrp30, AdipoQ, GBP-28, APM-1, ACDC.

Introduction:
Adiponectin is a recently discovered 244 amino acid protein, the product of the apM1 gene, which is physiologically active and specifically and highly expressed in adipose cells (Adipokine). The protein belongs to the soluble defense collagen super family; it has a collagen-like domain structurally homologous with collagen VIII and X and complement factor C1q-like globular domain. APM-1 forms homotrimers, which are the building blocks for higher order complexes found circulating in serum.

Description:
The Acrp30 Human Recombinant is fused with FLAG tag.

Source:
HEK293 (Human Embryonic Kidney cell line)

Purity:
Greater than 98% as determined by HPLC and SDS PAGE.

Activity in vitro:
In vitro gluconeogenesis assay in primary hepatocytes was performed, showing the Adiponectin human derived from mammalian cells can inhibit glucose production. The ED50 was ~6 µg/ml.

Formulation:
Sterile filtered and lyophilized from 0.5 mg/ml in PBS buffer.

Solubility:
Add 0.2 ml of deionized water and let the lyophilized pellet dissolve completely.

Stability:
For long term, store lyophilized AdipoQ at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C. The lyophilized protein remains stable for 24 months when stored at -20°C.

Applications:
ELISA, Western blotting, cell culture and/or animal studies.
Effect of human AdN on scavenger receptor A expression.
