A gas sensor protein is a type of protein that detects and responds to specific gaseous signaling molecules, playing a role in various biological processes and environmental sensing mechanisms. Protein-based gasoreceptors are generally found in the cytoplasm of cells.
Human Sar1A bound to GDP. The COPII coat consists of an inner layer – a flexible meshwork of Sar1, Sec23, and Sec24 – and an outer layer made of Sec13 and Sec31. [1] Sar1 resembles other Ras-family GTPases, with a core of six beta strands flanked by three alpha helices, and two flexible "switch domains".
Electron micrograph of in vitro–formed COPI-coated vesicles. Average vesicle diameter at the membrane level is 60 nm. COPI is a coatomer, a protein complex [1] that coats vesicles transporting proteins from the cis end of the Golgi complex back to the rough endoplasmic reticulum (ER), where they were originally synthesized, and between Golgi compartments.

Serum protein electrophoresis (SPEP or SPE) is a laboratory test that examines specific proteins in the blood called globulins. [1] The most common indications for a serum protein electrophoresis test are to diagnose or monitor multiple myeloma , a monoclonal gammopathy of uncertain significance (MGUS), or further investigate a discrepancy ...
Methods that screen protein–protein interactions in the living cells. Bimolecular fluorescence complementation (BiFC) is a technique for observing the interactions of proteins. Combining it with other new techniques, dual expression recombinase based methods can enable the screening of protein–protein interactions and their modulators. [1]
Top-down vs bottom-up proteomics. Top-down proteomics is a method of protein identification that either uses an ion trapping mass spectrometer to store an isolated protein ion for mass measurement and tandem mass spectrometry (MS/MS) analysis [1] [2] or other protein purification methods such as two-dimensional gel electrophoresis in conjunction with MS/MS. [3] Top-down proteomics is capable ...
The Bradford protein assay can measure protein quantities as little as 1 to 20 μg. [14] It is an extremely sensitive technique. The dye reagent is a stable ready to use product prepared in phosphoric acid. It can remain at room temperature for up to 2 weeks before it starts to degrade.
