The ligand N alpha, B1-(6-biotinylamido)hexanoyl-insulin was attached noncovalently to Sepharose 4B immobilized succinoylavidin to form an insulin-affinity resin. This resin was used to isolate highly purified insulin receptor from human placental tissue by a four step process involving (i) preparation of a crude membrane fraction, (ii) solubilization with Triton X-100, (iii) wheat germ agglutinin purification, and (iv) insulin-affinity chromatography. NaDodSO4/PAGE of the purified 125I-labeled receptor under nonreducing conditions showed the presence of a major component with an approximate molecular weight of 350,000 and a minor component with a molecular weight of approximately equal to 166,000. Based on the assumption that the degree of labeling is comparable in both components, the material corresponding to the Mr 350,000 peak represents approximately equal to 94% of the receptor preparation as determined by scanning the autoradiograms. The specific insulin binding capacity of the preparation is 18 +/- 6 micrograms of 125I-labeled insulin per mg of protein as determined by the polyethylene glycol assay and analyzed by Scatchard plot. Insulin binding activity was stable at 4 degrees C and pH 7.6 for at least 12 weeks but wa...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.
