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...Normal Human Serum-Single Donor from Innovative Research
Description:Normal Human Serum-Single Donor • Human serum is obtained from normal human donors who are found to be negative by a test for Human Immunodeficiency Virus Antigen (s) (HIV-1Ag), Antibodies to Human Immunodeficiency Virus (Anti-HIV 1/2), Hepatitis C Virus (HCV), and Nonreactive for Hepatitis B Surface Antigen (HbsAg) and Non-reactive by a screening test for syphilis. Serum is collected from a...Rabbit Serum Non-Hemolyzed, Sterile, Delipidized from Pel-Freez Biologicals
Description:Young rabbit blood (New Zealand White or Californian 8 - 10 weeks old, either sex) is refrigerated within 6 hours of collection, processed within 24 hours and frozen at -20ºC. The serum is then thawed in a cool waterbath, delipidized using a standard in-house protocol, filtered through a 0.22 micron filter, bottled, and refrozen at -20ºC....Serum Biomarker Chip from Whatman, Inc
Description:The first high-density serum biomarker chip to profile the relative abundance of cancer serum proteins. An antibody chip containing 120 human cancer serum biomarker-specific antibodies. A research tool that enables biomarker discovery scientists to study panels of biomarkers related to early detection, benefits of therapy and the likelihood of recurrence of cancer. Familiar gene expression chip f...Normal Pooled Human Serum from Innovative Research
Description:Normal Pooled Human Serum • Human serum is obtained from normal human donors who are found to be negative by a test for Human Immunodeficiency Virus Antigen (s) (HIV-1Ag), Antibodies to Human Immunodeficiency Virus (Anti-HIV 1/2), Hepatitis C Virus (HCV), and Nonreactive for Hepatitis B Surface Antigen (HbsAg) and Non-reactive by a screening test for syphilis. Sera are pooled from multiple d...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...Quantification of Nucleosomes in Serum by the Cell Death Detection ELISAplus
Cell death as a counterpart to cell proliferation plays anessential role in the homeostasis of cell numbers in adultorganisms, furthermore in eliminating cells damaged byirradiation, chemotherapeutic drugs, hyperthermia andother influences [1-3]. There are two distinct...Analysis of Blood Serum on the Liberty Series II ICP-AES with the axially-viewed plasma
...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...Serum Institute Launches New Tetanus-Diphtheria Vaccine
India's leading vaccine manufacturer Serum Institute of India has manufactured for the first time first indigenous Tetanus and Diphtheria (Td) vaccines // . The vaccine is called Td-Vac and will combat the deadly diphtheria and tetanus among both adolescents and adults. The new vaccine will replace the existing TT (Tetanus) vaccine, which is normally administered after an injury. <br...New tetanus-diphtheria combination vaccine launched by Serum Institute of India
A combination vaccine for immunization against tetanus and diphtheria, Td-Vac priced at Rs. 7.50 has been launched by Serum Institute of India // . The vaccine is aimed at combating the fatal tetanus and diphtheria (Td) in adolescents and adults. It is much different than the currently existing dual antigen vaccine used in children and would be used as an alternative to the TT (Tetanu...Higher Serum Selenium Linked With Reduced Risks of Prostate Cancer - in Some Men
Scientists Dr. Ulrike Peters, of the Fred Hutchinson Cancer Research Center, Seattle, and colleagues have come out with findings that show serum selenium or levels of selenium in// the blood is not that positively correlated with reduced risks of prostate cancer as previously thought. Previous studies have reported that the mineral is associated with reducing the risk of prostate and l...SAFE-T-FILL Serum Mini Capillary Collection Tubes
