Viruses infect host cells with their genetic material and then reproduce. They are found in humans, plants, bacteria and other places where they can infect cells, adapt and change. In celebration of Virus Appreciation Day, a day discover more about viruses, learn more about viruses in our infographic.

Cyanine dyes are members of the polymethine synthetic dye family historically used to increase photographic emulsion sensitivity. Cyanine dyes have versatile applications and are commonly used as fluorescent labels for proteins, nucleic acids, and small molecules. They are particularly suited for biomedical imaging, protein-protein interactions, proteomics, and transcriptomics. Different variants have distinctive spectral properties – for example, Cyanine dye 7 (Cy7) has a strong absorption peak at 747nm while Cyanine dye 5.5 (Cy5.5) has a strong absorption peak at 675nm.

Fas is a member of the tumor necrosis factor (TNF)-receptor superfamily and plays a key role in the physiological regulation of programmed cell death. This receptor contains a death domain which enables the formation of a signaling complex that includes Fas-associated death domain protein (FADD), caspase 8, and caspase 10. The auto-proteolytic processing of these complexed caspases triggers a downstream cascade that leads to membrane-mediated apoptosis.

CD56 is a member of the Ig super family and comprises five Ig-like domains and two extracellular fibronectin-type III domains. It is expressed as three major isoforms within the nervous system, on NK cells, and a specific set of T-cells. CD56+ NK and T-cells are unique in their ability to mediate cell-mediated cytotoxicity against certain tumor cell targets without MHC restriction. Other CD56 physiological functions include: mediating cell adhesion, triggering neurite extension and migration, and brain synapse formation.

CD34 is a cell-surface glycoprotein type 1 transmembrane protein that belongs to the sialomucin family. CD34 comprises of an intracellular cytoplasmic domain with consensus sites for serine, threonine, tyrosine and active protein kinase C (PKC). Because it is differentially glycosylated within different cell types, it has a range of apparent molecular weight sizes. It is a marker for pluripotent hematopoietic stem or progenitor cells and has been extensively used to isolate and characterize these progenitor cells.

September is Ovarian Cancer Awareness month and brings to focus a cancer that is estimated to be diagnosed in over 21,000 women in the US in 2014 (1). Ovarian cancer often goes undiagnosed due to the lack of symptoms until it metastasized into the pelvic or abdominal areas. Treatment typically requires surgery and chemotherapy.

Prostate specific membrane antigen (PSMA), also known as Glutamate carboxypeptidase II (GCPII), is a type II transmembrane glycoprotein that belongs to the M28 peptidase family. It acts as a glutamate carboxypeptidase on different substrates such as folate as well as the neuropeptide N-acetyl-l-aspartyl-l-glutamate. PSMA is expressed in a number of tissues including prostate, kidney, and both the central and peripheral nervous systems.

Green fluorescence protein (GFP) is a 27KD protein derived from the jellyfish Aquorea victoria that emits a green light (emission peak at a wavelength of 509 nm) when excited by blue light (excitation peak at a wavelength of 395 nm). GFP is a highly versatile protein that has become an invaluable tool in cell biology research because of its intrinsic fluorescence without substrate requirement, ability to be visualized over time durations - both short- and long-term - in living cells, and short sequence making it easy to clone and use an unobtrusive tag.

ITGB1BP2 is a muscle-specific protein cloned by a rat created by Branccio's group in Italy that was found to interact with the cytoplasmic domain of integrin beta 1¹. It is expressed only in heart and skeletal muscle but is not essential for normal development and differentiation of these tissues. Branccio's group published a follow-up study in Nature Medicine using an ITGB1BP2 antibody that the protein plays a critical role in sensing mechanical stress due to pressure overloading².

The Beta III tubulin protein is abundantly present in both the central and peripheral nervous systems (CNS and PNS), where it is predominantly expressed during fetal and postnatal development. In cerebellar and sympathoadrenal neurogenesis, Beta III distribution is neuron-associated and present in distinct temporal-spatial gradients that are dictated by the regional neuroepithelia of origin.
