These nucleotides are supplied as convenient, ready-to-use solutions in sterilized water. The 10 mM dNTP Mix contains all four dNTPs, each...

Interleukin 9, also known as IL9, is a cytokine (cell signalling molecule) belonging to the group of interleukins. The protein encoded by this gene is a cytokine produced by T-cells and specifically by CD4+ helper cells that acts as a regulator of a variety of hematopoietic cells. This cytokine...

The Vasoactive intestinal Peptide/Pituitary Adenylate Cyclase Activating Polypeptide (VPAC) receptor is G protein-coupled and has been divided into at least three types: PAC1, VPAC1, and VPAC2. High expression of PAC1 is observed in CNS and the adrenal medulla. Several splice variants of PAC1 result...

Human CD28 is composed of four exons encoding a protein of 220 amino acids that is expressed on the cell surface as a glycosylated, disulfide-linked homodimer of 44 kDa. Members of the CD28 family share a number of common features. These receptors consist of paired V-set immunoglobulin superfamily...

Tumor Necrosis Factor-Alpha (TNF-alpha) plays a major role in growth regulation, differentiation, inflammation, viral replication, tumorigenesis, and autoimmune disease. Besides inducing hemorrhagic necrosis of tumors, TNF has been found to be involved in tumorigenesis, tumor metastasis, viral...

The orexin/hypocretin peptides orexin A and orexin B (also known as hcrt-1 and hcrt-2) are 33- and 28-amino acid peptides, respectively. They are preferentially expressed in hypothalamus. The orexins have a range of physiological functions including feeding control, energy metabolism, neuroendocrine...

Chemokine (C-C motif) ligand 20 (CCL20) or liver activation regulated chemokine (LARC) or Macrophage Inflammatory Protein-3 (MIP3A) is a small cytokine belonging to the CC chemokine family. It is strongly chemotactic for lymphocytes and weakly attracts neutrophils, also known as LARC (Liver and...

SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. SARS-CoV-2 Nucleocapsid Protein is associated with nucleic acid. It is the most abundant protein for...

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 ß-defensins have been...

GenCRISPR™ ErCas12a Nuclease is an RNA-guided DNA endonuclease from Eubacterium rectale. Cas12a (previously known as Cpf1) belongs to the Class 2 Type V CRISPR/Cas system. Different from CRISPR/Cas9 system, the ribonucleoprotein (RNP) complex of CRISPR/Cas12a system is formed by Cas12a and...

Green fluorescence protein (GFP) is a 27 kDa protein derived from jellyfish Aequorea victoria .
