The GenBuilder Plus Cloning Kit enables seamless and one-step cloning of multiple DNA fragments into a linearized vector. The proprietary enzyme mix fuses together DNA fragments efficiently and precisely by recognizing 15-40 bp overlaps at the end of each fragment. The system allows cloning of DNA...

The prolactin releasing hormone receptor PRLHR also named PrRP receptor is a G-protein coupled receptor that binds the prolactin releasing hormone. RT-PCR analysis showed expression of PRLHR in the human brain, pituitaries, normal portions of adrenal glands and various tumor tissues. Northern blot...

Annexin V fluorescent conjugates can be used to detect apoptotic cells. The human anticoagulant Annexin V is a 35-36 kDa calcium-dependent phospholipid-binding protein with high affinity for phosphatidylserine (PS). In normal viable cells, PS is located on the inner leaflet of the cytoplasmic...

Fluorescent conjugates of Alpha-Bungarotoxin bind to the nicotinic acetylcholine receptor with high affinity, and thus can be used to image the distribution of the receptor at the neuromuscular junctions. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness,...

T lymphocytes are activated through MHC class II molecules on antigen-presenting cells (APC). After activation, T cells expand rapidly and secrete various cytokines. The Human CD3/CD28 T cell Activation Beads Kit is designed to activate and expand human T cells. This Kit contains Biotinylated...

BactoView™ Dead 655/670 is a novel far-red fluorescent DNA dye for no-wash staining of dead bacteria. Unlike traditional dyes like PI that readily stain live gram+ cells, BactoView™ Dead dyes selectively stain dead cells in both gram+ and gram- strains. 500X in water, 100 uL.

KE10059 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The mouse Thrombopoietin ELISA kit is to be used to detect and quantify protein levels of endogenous mouse Thrombopoietin. The assay recognizes mouse Thrombopoietin. An antibody specific for mouse Thrombopoietin...

The c-Myc protein is a transcription factor, encoded by the c-Myc gene on human chromosome 8q24. c-Myc is commonly activated in a variety of tumor cells and plays an important role in cellular proliferation, differentiation, apoptosis, and cell cycle progression. A synthetic peptide corresponding to...

Hepatocyte Growth Factor (HGF) ,also known as hepatopoietin-A and scatter factor, is a pleiotropic mitogen belonging to the peptidase S1 family (plasminogen subfamily). It is produced by mesenchymal cells and acts on epithelial cells, endothelial cells and haemopoietic progenitor cells. HGF binds to...

CTLA4 or CTLA-4 (cytotoxic T-lymphocyte-associated protein 4), also known as CD152 (cluster of differentiation 152), is a protein receptor that, functioning as an immune checkpoint, downregulates immune responses. CTLA4 is constitutively expressed in Tregs but only upregulated in conventional T...
