In healthy individuals, plasma cells originating from the bone marrow produce immunoglobulin molecules composed of two heavy chains and two light chains. There are two types of light chains in humans. The κ light chains are encoded by the immunoglobulin κ locus on chromosome 2 and λ light chains are encoded by the immunoglobulin λ locus on chromosome 22 [1]. During B lymphocyte development, the...

cell free dna (cfdna) is a genetic biomarker that is present in serum or plasma in high concentration in many types of cancer. identification of circu-lating cancer related dna molecules in serum or plasma is a non-invasive tool for early diagnosis and prognosis in many cancer patients. for this review, study selection and data extraction were performed by the authors. detection of point mutati...

Fetal bovine serum (FBS) is a ubiquitously used essential supplement in cell culture media. However, there are serious scientific and ethical concerns about the use of FBS regarding its harvest and production. During the last three decades, FBS could be substituted by other supplements or by the use of defined chemical components in serum-free cell culture. A number of serum-free medium formula...

Isolation of cell free fetal DNA (cffDNA) from maternal serum usually leads to very low concentrations of DNA impeding further resolving through conventional methods of electrophoresis. Although several protocols have been described for capillary electrophoresis (CE) of double stranded DNA, they usually need using special polymers or coated capillaries which degrade over time. Herein, we propos...

In this work, we present a study of the interaction between human serum albumin (HSA) and acetylsalicylic acid (ASA, C(9)H(8)O(4)) by molecular dynamics simulations (MD). Starting from an experimentally resolved structure of the complex, we performed the extraction of the ligand by means of the application of an external force. After stabilization of the system, we quantified the force used to ...

Human serum albumin has been used as a model protein for protein folding and ligand binding studies over many decades. Due to its long life period and high concentration in plasma, HSA is highly sensitive to glycation. It is reported that 175 mg/dL glucose concentration is a threshold of kidney activity for the beginning of excretion of glucose. pH denaturation of HSA in absence and presence of...
