Anti-HSF2 Rabbit Polyclonal Antibody

Catalog Number: (89358-042)
Supplier: Genetex
Description: HSF2, as well as the related gene HSF1, encodes a protein that binds specifically to the heat-shock element and has homology to HSFs of other species. Heat shock transcription factors activate heat-shock response genes under conditions of heat or other stresses. Although the names HSF1 and HSF2 were chosen for historical reasons, these peptides should be referred to as heat-shock transcription factors. [provided by RefSeq]

Anti-HSP27 Chicken Polyclonal Antibody

Catalog Number: (10782-000)
Supplier: Biosensis
Description: The heat shock proteins were discovered, as the name suggests, since they are heavily upregulated when cells are stressed by temperatures above the normal physiological range. They are expressed in unstressed cells also and have a normal function as chaperones, helping other proteins to fold correctly, and are required in much greater amounts if the cell or tissue is stressed by heat. The increased levels are generated transcriptionally under the influence of a powerful transcription factor, the heat shock factor 1 (HSF1). The different heat shock proteins were originally named based on their SDS-PAGE mobility, so HSP27 has an apparent molecular weight of 27kDa. It is an abundant protein even under non-stress conditions and frequently shows up as a major spot on 2 dimensional gels of cells or tissues. It is known to associate with a variety of other proteins such as actin, intermediate filament subunits and ubiquitin and is found both in the cytoplasm and the nucleus of cells. HSP27 can become heavily phosphorylated under the influence of multiple protein kinases particularly as a result of activation of the p38/SAPK pathway. Upregulation of this protein is protective against neurodegenerative diseases at least in certain mouse models (1). Point mutations in the HSP27 gene are associated with two neurological diseases, Charcot-Marie-Tooth disease type 2F and distal hereditary motor neuropathy IIB (2). These diseases are associated with axonal loss apparently following defects in the transport of neurofilaments.

Anti-HSF1 Rabbit Polyclonal Antibody

Catalog Number: (76262-728)
Supplier: Rockland Immunochemical
Description: Anti-HSF1 Antibody was designed, produced, and validated as part of the Joy Cappel Young Investigator Award (JCYIA). Heat shock factor 1 (HSF1) is a highly conserved transcription factor that coordinates stress-induced transcription and directs versatile physiological processes in eukaryotes. Upon stress, HSF1 is the key transcriptional activator of chaperones, co-chaperones and ubiquitin, and also coordinates the expression of many transcriptional and translational regulators, signaling molecules and mitotic determinants. HSF1 is involved in balancing core cellular processes during stress and enables their rapid re-establishment once conditions suitable for proliferation have been restored. Importantly, HSF1 controls a distinct set of target genes in cell stress, development and cancer progression. The central role of HSF1 in diverse cellular functions is reflected in pathologies, such as neurodegenerative diseases and cancer, where an imbalance in HSF1 activity facilitates disease onset. The ability of cancer cells to harness HSF1 for metastatic progression highlights the plasticity of HSF1 in rewiring transcription and coordinating cellular processes. Anti-HSF1 antibody is thus ideal for investigators involved in cancer research and neurodegenerative diseases.

Anti-HSPA6 Rabbit Polyclonal Antibody (Alexa Fluor® 750)

Catalog Number: (76118-334)
Supplier: Bioss
Description: In cooperation with other chaperones, Hsp70s stabilize preexistent proteins against aggregation and mediate the folding of newly translated polypeptides in the cytosol as well as within organelles. These chaperones participate in all these processes through their ability to recognize nonnative conformations of other proteins. They bind extended peptide segments with a net hydrophobic character exposed by polypeptides during translation and membrane translocation, or following stress-induced damage. Sequence similarities Belongs to the heat shock protein 70 family.

Human Recombinant Heat Shock beta 11 (from E. coli)

Catalog Number: (75789-178)
Supplier: Prosci
Description: Heat Shock Protein beta -11 (HSPB11) is a stress-responsive protein that is required to deal with proteotoxic stresses. HSPB11 is composed of an IFT complex B composed of IFT88, IFT57, TRAF3IP1, IFT52, IFT27, HSPB11 and IFT20 and is detected in placenta. HSPB11 has beeb shown to form oligomeric complexes and prevent the aggregation of in vitro denaturated aldolase and glyceraldehyde-3-phosphate dehydrogenase in accordance with the chaperone model of HSPB1 and HSPB5. HSPB11 overexpression protected against etoposide-induced cell death that correlated with a decreased release of mitochondrial Cytochrome C into the cytosol. Inhibition of HSP90 function completely abrogated the protective effect of HSPB11. This data suggests that at least in the case of HSPB11, interaction with other chaperone machines besides HSPA1A may contribute to functional specificity and cellular functioning.

Anti-HSP20 Rabbit Polyclonal Antibody (Alexa Fluor® 680)

Catalog Number: (76100-746)
Supplier: Bioss
Description: Hsp20 is a small heat shock protein related to Hsp25, Hsp27 and may form different hetercomplexes with these proteins. The specific physiological function of Hsp20 is not yet known. It is distributed ubiquitously in tissues, but is found in higher levels in skeletal, smooth and heart muscle. Under normal conditions, Hsp20 is diffusely distributed in the cytosol, but under heat stress conditions, it translocates to the nucleus. Unlike other heat shock proteins the amount of Hsp20 does not increase after heat shock. The Hsp20 was demonstrated to constitute up to 1.3% of the total cellular protein in vertebrate tissues, especially in muscle, and its expression is related to muscle contraction, specifically in slow-twitch muscle. Hsp20 may form different heterocomplexes with other Hsp's, such as alpha-crystalline and Hsp25. Phosphorylated form of Hsp20 is proposed to interact with monomeric actin whereas dephosphorylated form binds polymeric actin filaments. In normal conditions Hsp20 is diffusely disturbed in cytosol but under the heat stress it undergoes translocation to membrane fraction.

Anti-HSF1 Rabbit Polyclonal Antibody

Catalog Number: (10414-080)
Supplier: Bioss
Description: Two HSFs have been identified in human cells, HSF 1 and HSF 2, which bind to the same HSEs and have 38% sequence identity. These factors are activated by distinct stimuli, HSF 1 is responsive to classical stress signals such as heat, heavy metals and oxidative reagents, whereas HSF 2 is activated during hemin-mediated differentiation of human erythroleukemia cells.HSF 1 exists constitutively in the cytoplasm and the nucleus of unstressed cells as a monomer which lacks DNA binding activity. Through an unknown signal generated during stress, HSF 1 becomes activated to a nuclear localized, trimeric state which binds to DNA. The phosphorylation of HSF 1 is necessary for maximal transcription of heat shock genes.

Anti-HSPD1 Mouse Monoclonal Antibody (CF488A) [clone: HSPD1/780]

Supplier: Biotium
Description: This antibody recognizes a 60 kDa protein, identified as the heat shock protein 60 (hsp60). A wide variety of environmental and pathophysiological stressful conditions trigger the synthesis of a family of proteins known as heat shock proteins (HSPs), more appropriately called as stress response proteins (SRPs). Hsp60 is a potential antigen in a number of autoimmune diseases. In human arthritis and in experimentally induced arthritis in animals, disease development coincides with the development of immune reactivity directed against not only bacterial hsp60, but also against its mammalian homolog.

CF® dyes are Biotium's next-generation fluorescent dyes. CF®488A is a green fluorescent dye (Ex/Em 490/515 nm) with excellent brightness and photostability. The dye is minimally charged for less non-specific binding. CF®488A also is compatible with super-resolution imaging by TIRF.

Human Stresscopin

Supplier: Bachem Americas
Description: Stresscopin is a specific ligand for the corticotropin-releasing hormone receptor type 2 (CRHR2). Transcripts are expressed in brain and most tissues analyzed. Intraperitoneal injections of stresscopin suppresses heat-induced edema formation in anesthetized rats. It also decreases food intake and exhibits an inhibitory effect on gastric emptying activity. This CRHR2 agonist might represent an endogenous ligand for maintaining homeostasis after stress.
