Welcome to OriGene’s Test Your COVID-19 IQ Challenge Series Part Two
Jul 01, 2020
We have been bombarded with information on COVID19 from the beginning of this year after the first case of COVID19 was diagnosed. I tried to keep up but with 6000+ papers published in the first two months that was hard to keep up. Then one day a 2nd grader asked a simple question ‘What is COVID19’? I tried to explain the disease, symptoms and causes...

ACE2: Receptor for COVID-19 Invasion
Feb 28, 2020
The recent outbreak of COVID-19 that started in Wuhan, China, has spread globally and caused major loss in human lives. The latest research has reported that ACE2 (angiotensin converting enzyme 2) is a functional receptor for COVID-19 to latch on and enter.View All COVID19 Products The coronavirus enters human cell through the interaction of virus Spike protein (S protein) and ACE2 receptor on the cell...
The Revival of Lentiviral Vectors
Dec 11, 2019
In the early 1990s, researchers set out to harness viruses for gene therapy applications. The idea was to co-opt a virus’ natural ability to target cells, transverse the membrane and deliver genetic cargo for novel gene-based therapies. But like many early-stage technologies, challenges, setbacks and missteps dampened initial enthusiasm. Lentivirus-based vectors are increasingly used in gene and cell therapy research because theyhave the ability to...
"Where do you get your protein?" Survey Results
Apr 08, 2019
Recently, OriGene conducted a survey in our scientific community on proteins that scientists use in their research. Over 900 scientists responded to the survey worldwide. Below are some of the questions on the survey: Where do you get your proteins? How do you find your proteins? Which of the followings is the top factor you consider when selecting a protein product? What are the downstream...
Tips on Molecular Cloning
Mar 12, 2019
Molecular cloning is a set of experimental methods in molecular biology that are used to assemble recombinant DNA molecules. These recombinant molecules are used to direct their replication within host organism (1,2). In this article, we describe the basic molecular cloning technique that helps every scientist in their laboratory on a regular basis. Plasmid based cloning comprises of 4 main steps: Insert DNA preparation Vector...
HSD17B13 (Hydroxysteroid 17-Beta Dehydrogenase 13)
Jan 23, 2019
HSD17B13, a member of a large family of 17β-hydroxysteroid dehydrogenases, gained a sudden fame recently. A genetic study in 2018 discovered that a genetic variant is associated with a reduced risk for chronicle liver diseases, including NAFLD (non-alcoholic fatty liver disease) and NASH (non-alcoholic steatohepatitis). More studies indicate the progress of NASH to HCC can also be reduced by the presence of the variant. Clin...
2018 Nobel Prize in Medicine Awarded to 2 Immunotherapy Researchers
Oct 23, 2018
The 2018 Noble Prize in Physiology or Medicine was awarded on Monday, October 1st, 2018 to Tasuku Honjo of Japan and James P. Allison of the United States for discovering Immuno Oncology Checkpoint Proteins (I-O) that have fundamentally changed the way some cancers are treated. Unlike previous cancer therapies that target cancer cells directly, their discovery targets the “brakes” of the host immune system. Role...

MAGEA4 is Hot Right Now!
Jul 16, 2018
What makes MAGEA4 a hot target? Melanoma Antigen Gene (MAGE) type A4 acts as an activator of Trans-lesion synthesis, an error-prone mechanism for DNA repair. Interest in the antigen began when the MAGE proteins were found to only express in the testes, placenta, and several types of tumors. This differentiation made MAGEA4 a perfect immunotherapeutic target, and the excitement in the research community ignited. A...
Biosafety considerations when handling lentivirus
Jun 14, 2018
Human ingenuity has turned the sinister HIV-1 virus into a convenient laboratory tool for gene delivery as lentiviral vector. After multiple rounds of engineering, the 3rd generation of lenti viral system has diminished the possibility for the lab-made virus to replicate and to impose health risk to laboratory staff. While it is important that we treat all laboratory tools with respect, there is no reason...
Antibody Validation – How do we confirm the specificity of an antibody?
May 12, 2018
One common question that scientists always ask when they get the signal from an antibody based assay is: "Does this signal truly represent the presence and quantity of my protein?" Antibody specificity is always a concern for scientists. Even though there are a number of validation methods that have been used for the specificity testing, the data is often over-interpreted. Research data from various groups...
