Background Hsp70 genes encode abundant heat-inducible 70-kDa hsps (hsp70s). In most eukaryoteshsp70 genes exist as part of a multigene family. They are found in most cellularcompartments of eukaryotes including nuclei, mitochondria, chloroplasts, theendoplasmic reticulum and the cytosol, as well as in bacteria. The genes show a highdegree of conservation, having at least 5O% identity (2). The N-terminal two thirds ofhsp70s are more conserved than the C-terminal third. Hsp70 binds ATP with high affinityand possesses a weak ATPase activity which can be stimulated by binding to unfoldedproteins and synthetic peptides (3). When hsc70 (constitutively expressed) present inmammalian cells was truncated, ATP binding activity was found to reside in an N-terminalfragment of 44 kDa which lacked peptide binding capacity. Polypeptide binding abilitytherefore resided within the C-terminal half (4). The structure of this ATP binding domaindisplays multiple features of nucleotide binding proteins (5). All hsp70s, regardless of location, bind proteins, particularly unfolded ones. The molecularchaperones of the hsp70 family recognize and bind to nascent polypeptide chains as wellas partially folded intermediates of proteins preventing their aggregation and misfolding. The binding of ATP triggers a critical conformational change leading to the release of thebound substrate protein (6). The universal ability of hsp70s to undergo cycles of binding toand release from hydrophobic stretches of partially unfolded proteins determines their rolein a great variety of vital intracellular functions such as protein synthesis, protein foldingand oligomerization and protein transport.

UniProt P11142
Application Notes Western blot (7): 1 µg/mL was sufficient for detection of hsp70/Hsc70 in 20 g of HeLalysate.
Restrictions For Research Use only
Format Liquid
Concentration 1.0 mg/mL
Buffer PBS pH 7.2 0.09 % Sodium Azide 50 % Glycerol
Preservative Sodium azide
Precaution of Use WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice Avoid repeated freezing and thawing.
Storage 4 °C/-20 °C
Storage Comment Store the antibody at 2 - 8 °C up to one month or (in aliquots) at -20 °C for longer. Shelf life: one year from despatch.
Expiry Date 12 months
