Apoptosis and necrosis are two major processes by which cells die. Apoptosis is an active, genetically regulated disassembly of the cell from within. During apoptosis, phosphatidylserine (PS) is translocated from the inner to the outer surface of the cell for phagocytic cell recognition. The human...

Members of the Hedgehog (Hh) family are highly conserved proteins which are widely represented throughout the animal kingdom. The three known mammalian Hh proteins, Sonic (Shh), Desert (Dhh) and Indian (Ihh) are structurally related and share a high degree of amino-acid sequence identity (e.g., Shh...

One-Step Lumitein™ Protein Gel Stain is a ready-to-use luminescent red protein gel stain. It is a dramatically improved version of our original Lumitein™ protein gel stain for convenience and safety.

NBD fluoride (4-Fluoro-7-nitrobenzo-2-oxa-1,3-diazole) is similar to NBD chloride except that the former is much more reactive toward amines. Both reagents are nonfluorescent until they react with primary or secondary amines to produce a fluorescent product. NBD chloride and NBD fluoride have been...

Biotin-16-dUTP can be enzymatically incorporated into DNA via nick translation, random priming, or 3' end terminal labeling. The terminal deoxynucleotidyl transferase (TdT)-mediated biotin-dUTP nick end-labeling (TUNEL) method has been commonly used for apoptosis studies. The number '16' is the...

CF® dye with tetrazine reacts with cyclooctene (TCO, methylcyclopropene) labeled molecule via copper free click chemistry. This copper free bioorthogonal reaction is useful for staining the surface of live cells or when there are concerns about native protein function loss with copper in cell...

KE00287 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The LDH-B ELISA kit is to be used to detect and quantify protein levels of endogenous LDH-B. The assay recognizes human LDH-B. An antibody specific for LDH-B has been pre-coated onto the microwells. The LDH-B...

CR110-C5-maleimide (full name: 5(6)-Carboxyrhodamine 110-C5-maleimide) is a maleimide derivative of the green fluorescent dye carboxyrhodamine 110. The dye has spectral properties (&lamba; _Ex/&lamba; _Em (MeOH) = 502/524 nm) similar to those of fluorescein...

Streptavidin conjugates are high quality streptavidin biotin binding protein labeled with CF® dyes and a selection of other labels. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent...

Nivolumab (Opdivo) is a humanized monoclonal antibody that is approved by the U.S. Food and Drug Administration for the trea™ent of patients with unresectable or metastatic melanoma. Nivolumab binds to the human cell surface receptor PD-1 (Programmed Cell Death Protein 1) and blocks its...

Single donor specimens collected from donors prior to and continuing through disease progression.

Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. The ª-defensins are distinguished from the ß-defensins by the pairing of their three disulfide bonds. To date, four human ß-defensins have been...

KE10107 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The mouse Tnfrsf11b ELISA kit is to be used to detect and quantify protein levels of endogenous mouse Tnfrsf11b.
