Antibodies

Sterol regulatory element binding proteins (SREBPs) are indirectly required for cholesterol biosynthesis and for uptake and fatty acid biosynthesis. There are three known SREBP isoforms, SREBP1a, 1c and SREBP2; these have different roles in lipid synthesis.

The Myosin superfamily is a large and diverse protein family, and its members are grouped into many classes, are involved in a number of cellular pathways (1). Myosins contain actin- and ATP-binding sites in their conserved catalytic head domain and localize to a number of intracellular compartments and participate in many trafficking and anchoring events.

Secretory granule-mediated cell death is one of the the key mechanisms for elimination of virus-infected and transformed target cells by cytotoxic lymphocytes.

Synaptophysin a Marker Protein in Neuroendocrine Cells Synaptophysin is a major integral membrane glycoprotein of neuronal synaptic vesicles present in virtually all synapses and shows a high degree of evolutionary conservation across the mammals. Synaptophysin has been detected in numerous endocrine cell types and is localized in the membrane of small synaptic-like vesicles.

MyD88, also called myeloid differentiation primary response gene 88, encodes a cytosolic adapter protein that plays an essential role in innate and adaptive immune responses. The innate immune system recognizes the presence of bacterial pathogens through the expression of a family known as Toll-like receptors (TLRs).

Expression of transgenes in complex organisms is accompanied by the need for a specific and sensitive detection of a target protein. One familiar approach is the use of a protein-specific antibody. However, antibodies raised against to your protein of interest may not always be available, are often costly or time-consuming to produce, and are usually not target specific (1). Moreover antibodies are often not suitable for several applications and immunohistochemical detection is a frequent bottleneck.

Ubiquitin is an abundant and essential cellular 9-kd protein that is conserved across evolution from yeast to humans. Ubiquitin is used by cells as a covalent modifier of other proteins both to activate their function and to target them for degradation, depending on the degree of ubiquitination.

 Tyrosine hydroxylase catalyzes the rate-limiting step in the biosynthesis of the catecholamines dopamine, norepinephrine, and epinephrine. A hallmark of Parkinson's disease is the loss of dopaminergic neurons in the substantia nigra. Mutations in cases of autosomal recessive dopa-responsive dystonia and infantile Parkinsonism have also been identified recently.

Platelet endothelial cell adhesion molecule PECAM1 (also called CD31) is a 130 kDa type I transmembrane glycoprotein that is expressed on most cells of the hematopoietic lineage including platelets, monocytes, neutrophils and certain lymphocyte subsets (1). It has also been suggested that PECAM-1 contributes to endothelial cell barrier function.
