Recombinant proteins support modern research in powerful ways from enzyme assays and binding studies to standards for immunoassays and structural biology. When a protein is stored properly, experiments run smoothly,...

If you’ve ever run an ELISA and felt like your results were “almost perfect” but not quite consistent—high background in a few wells, edge effects, or bigger-than-expected variability—your wash steps...

Choosing the right PCR tubes is one of those small decisions that can make PCR workflows feel effortlessly smooth—or unnecessarily finicky. The good news is that this choice becomes simple...

Safe immunization programs depend on more than the vaccine itself—they depend on a reliable cold chain. If vaccines are exposed to temperatures outside their labeled range, they can lose potency,...

In any molecular biology lab, success with PCR starts long before the thermocycler lid closes. It begins with the plasticware you choose. The right PCR pipette tips and PCR tubes...

When you run an ELISA, the colored wells or light signals are just the beginning. What really matters is how you read the ELISA results: are they qualitative, quantitative, or...

In almost every immunology or clinical lab, the ELISA plate is a daily companion. Behind every clear or colored well lies the same fundamental concept: an ELISA antibody binding its...

An antibody test (often called an antibody test or serology test) is a simple blood test that tells a much deeper story about your immune system. Instead of looking directly...

Western blotting turns a messy protein mix into a readable picture. When it works, you see clear bands at the expected molecular weights; when it doesn’t, you’re staring at foggy...

The western blot test is one of those medical–lab terms people usually meet after a first screening test. You do an ELISA or EIA. It comes back positive or unclear....

Vector cloning sits right in the middle of molecular biology. Any time you want to move a piece of DNA from “I amplified it” to “I can store, express, or...

Cell culture has gone through a quiet evolution. For a long time, almost every experiment was done in flat, two-dimensional (2D) monolayers. Now, three-dimensional (3D) cell culture is showing that...
