New journal article urges use of animal serum-free media for growing live cells

In the March issue of Trends in Biotechnology, scientists and doctors with the Physicians Committee for Responsible Medicine (PCRM) recommend using only animal serum-free media to grow live cells in the laboratory. At issue is the use of fetal calf serum, which is obtained by puncturing the heart of a fetal calf without anesthesia. Recent breakthroughs permit the growth of human cells in a medium...

New culture method for hepatitis C virus uses primary hepatocytes and patient serum

Researchers open the way for improved study of hepatitis C virus by devising a novel virus culture system that allows replication of patient-isolated virus in nontransformed hepatocytes, instead of culture-adapted virus strains in transformed cell lines. The related report by Lázaro et al, "Hepatitis C virus replication in transfected and serum-infected cultured human fetal hepatocytes," appears...

Liver cancer patients with high serum levels of hepatitis B virus face poorer outcomes

In the June issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD), researchers report their findings from the first-ever study examining the prognostic value of serum HBV DNA levels for patients with liver cancer undergoing chemotherapy. They found that patients with high pre-chemotherapy levels of HBV DN...

Factor B-depleted serum from Quidel

Description:Quidel's depleted sera are specifically depleted of a single complement protein. With the exception of the depleted protein, the alternative and classical pathways are left intact. These reagents are therefore ideal for the detection and quantitation of hemolytically active complement components. Depleted sera have been used to assess complement activation in non-human species. A copy of the mon...

Affinity Depletion Cartridges for Removal of Human Serum Albumin and Immunoglobulins from Human Serum

One of the major difficulties in analyzing the proteome of human serum is the dynamic range of the concentrations of the proteins present in the sample. Human serum albumin (HSA) constitutes 57-71% of total serum protein and gammaimmunoglobulin (IgG) ranges from 8-26%. Removal of these two proteins alone clears about 75% of t...

Protein Depletion for Plasma and Serum Proteomic Analysis

Human plasma and serum represents an important biological material for disease diagnosis. However, the wide dynamic range in protein concentration remains a major challenge in the development of diagnostic assays for the very low concentration of biomarker proteins in the presence of high abundance proteins. A practical and effect...

Serum Progesterone Helps Stratify Ectopic Pregnancy Risk

Measurement of serum progesterone levels may be helpful in deciding which emergency department patients with no strong clinical signs are at low risk of ectopic pregnancy, according to a report in the August issue of the Annals of Emergency Medicine. They measured progesterone levels in 716 first-trimester patients who presented to an emergency department with abdominal pain or...

Relationship Between Serum Dioxin Levels And Age At Menopause

Recent research published in the July issue of the journal Environmental Health Perspectives, demonstrates a non-monotonic dose-response relationship between serum TCDD levels and age of onset of natural menopause//. The age of onset of menopause is believed to reflect the rate of atrophy of the ovarian follicles. Alterations in age at menopause can have important health implications be...
