A simple scheme for large scale purification of urine - Derived Bence Jones Kappa protein.

We have investigated and optimized purification process, suitable for industrial scale, to obtain high purity grade Bence Jones Kappa Protein ('BJK-Protein'), while preserving its physiological properties and functions. BJK-Protein was obtained from a biological waste product i.e.

An improved protocol for large scale production of high purity 'Fc' fragment of human immunoglobulin G (IgG-Fc).

We describe a simplified approach for purification and characterization of human 'IgG-Fc' fragment used widely as immunochemical tool and for therapeutic purposes. The 'Fc' fragment was purified from human IgG in a 3-stage column chromatography. The purified 'Fc' fragment appeared as a dimer glycoprotein with an apparent molecular mass of 52,981 Dalton (Ultraflex MALDI TOF/TOF).

A cost-effective method for purification and characterization of human urinary albumin.

We describe a simplified approach for the purification and characterization of urinary albumin, a key biomarker currently used for understanding the onset and prognosis of microalbuminuria. Urinary albumin was purified from human urine collected from diabetic kidney disease patients by using 2-stage tangential flow filtration process and set of column chromatography steps. The relative molecular mass of urinary albumin is 66,871 Da (SYNAPT G2 High Definition Mass Spectrometry System).

Relationship between depressive symptom severity and amygdala volume in a large community-based sample.

Amygdala is an affective processing center that regulates and assigns valence to different emotions and has been implicated in the pathophysiology of mood disorders. This population-based study employed a community sample of 1747 adults to examine relationships between amygdala volume and depressive symptom severity. Neuroimaging data from participants in the Dallas Heart Study were used.

Microtubule associated protein 2 in bipolar depression: Impact of pregnenolone.

Background: Pregnenolone, and related neurosteroids, may have antidepressant properties. Preclinical research proposes that microtubule associated protein 2 (MAP2) binding may be a mechanism for antidepressant properties of pregnenolone. Thus, MAP2 might be a novel target for antidepressant therapy.
