The SOCS2 Ubiquitin Ligase Complex Regulates Growth Hormone Receptor Levels

Immunoprecipitation assay It is the technique of precipitating a protein “antigen” out of solution using “an antibody” that specifically binds to that particular protein “antigen” in a complex This process can be used to isolate and concentrate a particular protein from a sample containing many thousands of different proteins Immunoprecipitation requires that the antibody be[…]

The Acylation Stimulating Protein as a Lipogenic Factor in Women

Abstract: Objective: The menstrual cycle represents a continuous state of change in terms of female sex steroid environment which are believed to affect fat storage and distribution in women. Progesterone is linked to increased fat storage while estrogen exerts anti- lipogenic effects. In this study, we investigate variations in the potent lipogenic factor, the acylation[…]
