Human Recombinant Enterokinase (from CHO cells)

Supplier: Peprotech
Description: Proteases (also called Proteolytic Enzymes, Peptidases, or Proteinases) are enzymes that hydrolyze the amide bonds within proteins or peptides. Most proteases act in a specific manner, hydrolyzing bonds at, or adjacent to, specific residues, or a specific sequence of residues contained within the substrate protein or peptide. Proteases play an important role in most diseases and biological processes, including prenatal and postnatal development, reproduction, signal transduction, the immune response, various autoimmune and degenerative diseases, and cancer. They are also an important research tool, frequently used in the analysis and production of proteins. Enterokinase sequentially cleaves carboxyl side of D-D-D-D-K. Human Enterokinase is expressed as a linear 1019 amino acid polypeptide precursor glycoprotein. Proteolytic processing of this precursor generates the biologically active form of Enterokinase, which consists of two polypeptide chains (heavy chain and light chain) held together by a single disulfide bond, resulting in formation of a biologically active heterodimer. The heavy chain consists of 784 amino acid residues, and the light chain consists of 235 amino acid residues. The calculated molecular weight of Recombinant Human Enterokinase is 108.7 kDa.

Anti-CD38 Mouse Monoclonal Antibody [clone: 3C6G4]

Catalog Number: (10084-344)
Supplier: Proteintech
Description: CD38 is also named as ADP-ribosyl cyclase 1 and belongs to the ADP-ribosyl cyclase family. The CD38 cDNA sequence predicts an unusual 30 kDa polypeptide with a short N-terminal cyto- plasmic tail, and a carboxyl-terminal extracellular domain carrying the four potential N-linked glyco- sylation sites. It usually acts as a 45 kDa bifunctional ectoenzyme that catalyzes the synthesis of cyclic ADP-ribose (cADPR) from NAD1 and the hydrolysis of cADPR to ADP-ribose. It has 2 isoforms produced by alternative splicing. This antibody is specifci to CD38.

SMCC (N-Succinimidyl 4-(N-Maleimidomethyl)cyclohexanecarboxylate), Pierce™

Catalog Number: (CAPI22360)
Supplier: Thermo Scientific
Description: Thermo Scientific Pierce SMCC is a hetero-bifunctional crosslinker that contain N-hydroxysuccinimide (NHS) ester and maleimide groups that allow covalent conjugation of amine- and sulfhydryl-containing molecules. NHS esters react with primary amines at pH 7–9 to form amide bonds, while maleimides react with sulfhydryl groups at pH 6.5–7.5 to form stable thioether bonds. In aqueous solutions, NHS ester hydrolytic degradation is a competing reaction whose rate increases with pH. The maleimide group is more stable than the NHS-ester group, but will slowly hydrolyze and lose its reaction specificity for sulfhydryls at pH values > 7.5. For these reasons, conjugations with these crosslinkers are usually performed at pH 7.2–7.5, with the NHS ester (amine-targeted) reacted before or simultaneous with the maleimide (sulfhydryl-targeted) reaction.

Human Recombinant alpha-Synuclein (from E. coli), HiLyte Fluor® 488

Catalog Number: (103004-984)
Supplier: Anaspec Inc
Description: The recombinant human a-synuclein (1-140) (GenBank Accession # NP_000336) was expressed and purified from E. coli and conjugated with the fluorescence dye HiLyte FluorTM 488. This protein is produced without affinity tag.
α-Synuclein is a major component of Lewy bodies in the affected neurons in Parkinson's disease. This protein has a mass of 14.5 kDa (140 amino acids long) and consists of a conserved degenerative amino-terminal domain and an acidic carboxyl-terminal with higher sequence divergence. α-Synuclein is predominantly expressed in brain, specifically in cerebellum, thalamus, neocortex, hippocampus, and striatum regions. Other tissues express α-Synuclein at very low levels. The physiological role of α-synuclein is not yet well understood. However, the presence of imperfect KTKEGV lipid interacting repeats suggests that it may be involved in synaptic vesicle homeostasis.

5(6)-Carboxyfluorescein

Supplier: Anaspec Inc
Description: Although FITC reagents have been more often used to prepare fluoresceinated bioconjugates, the low stability of FITC bioconjugates makes some researchers use amine-reactive succinimidyl esters of carboxyfluorescein (commonly called FAM) in bioconjugations. FAM reagents give carboxamides that are more resistant to hydrolysis. We have shown that FAM reagents require less stringent reaction conditions and give better conjugation yields, and the resulted conjugates have superior stability. We noted that FITC labeled peptides tend to deteriorate more quickly than the corresponding FAM conjugates.

Anti-Acetyl Coenzyme A Carboxylase beta Ser220 Rabbit Polyclonal Antibody

Catalog Number: (77440-402)
Supplier: Bioss
Description: Acetyl-CoA carboxylase (ACC) is a complex multifunctional enzyme system. ACC is a biotin-containing enzyme which catalyzes the carboxylation of acetyl-CoA to malonyl-CoA, the rate-limiting step in fatty acid synthesis. There are two ACC forms, alpha and beta, encoded by two different genes. ACC-alpha is highly enriched in lipogenic tissues. The enzyme is under long term control at the transcriptional and translational levels and under short term regulation by the phosphorylation/dephosphorylation of targeted serine residues and by allosteric transformation by citrate or palmitoyl-CoA. Multiple alternatively spliced transcript variants divergent in the 5' sequence and encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008].

Anti-Cortactin Thr466 Rabbit Polyclonal Antibody

Catalog Number: (77437-542)
Supplier: Bioss
Description: Cortactin is an 80/85 kDa cytoskeleton protein that facilitates assembly of cortical actin. Cortactin is widely expressed in most adherent cells and is a prominent substrate of protein tyrosine kinase Src in vivo and in vitro. The protein sequence of cortactin contains multiple amino terminal tandem repeats of a unique 37 amino acid sequence, which associates with actin, and a Src homology 3 (SH3) domain at the carboxyl terminus. Between the repeat and the SH3 domain, there is an alpha helical structure followed by a proline rich region. Between the proline rich region and the SH3 domain, there are a series of Src phosphorylation sites (Tyr421, Tyr470, and Tyr486). In vitro, cortactin binds to and cross links F actin into meshworks.

Anti-RCAN2 Rabbit Polyclonal Antibody

Catalog Number: (10460-048)
Supplier: Bioss
Description: Calcineurin is a Ca(2+) dependent protein phosphatase that is involed in several neuornal functions. Proteins belonging to the RCAN (Regulator of calcineurin) family modulate the activity of Calcineurin through a valine-rich region within their carboxyl tail. RCANs compete with NFATs (Nuclear factor of activated T-cells) for binding to the same docking site in calcineurin, which results in either inhibition or activation of calcineurin activity. Calcipressin-2, also known as RCAN2 and DSCR1L1 (Down syndrome candidate region 1-like 1), is a 197 amino acid protein that is highly expressed in both the cytoplasm and nucleus of neurons and is the only RCAN family member that is found in glial cells. Calcipressin-3, also known as RCAN3 and DSCR1L2 (Down syndrome candidate region 1-like protein 2), is a 241 amino acid protein that potentially is involved in central nervous system development. Calcipressin-3 interacts with cardiac troponin I, suggesting that it may play a role in cardiac contraction events.
