Keyhole limpet hemocyanin (KLH) is a large cooper-containing protein consisting of subunits with MW of 400 kDa. It is found in the hemolymph of the sea mollusk Megathura crenulata. This extracellular respiratory protein has many immunostimulatory properties, including the ability to enhance the host’s immune response by interacting with T cells, monocytes, macrophages, and polymorphonuclear lymphocytes. Since its discovery, KLH has been used primarily as a carrier for vaccines and antigens and as adjuvant treatment in regimens such as antimicrobial therapy.
Product Type:
Antibody
Antibody Type:
Polyclonal
Format:
Lyophilized
Storage Temp:
Store lyophilized/reconstituted at -20 °C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
Host Animal:
Rabbit
Species Reactivity:
Megathura crenulata - most commonly used carrier protein
Antibody can be used as a negative control to determine if observed signal is generated by anti-KLH or anti-peptide antibodies, Due to its large size KLH protein will be very difficult to separate on SDS-PAGE

1: 10 000 (ELISA), 1: 10 000 (WB), 1: 1000 (IL)
Purity:
Immunogen affinity purified serum in PBS pH 7.4.
Reconstitution:
For reconstitution add 50 l of sterile water
Molecular Weight:
ca, 400 kDa/subunit

Special application note:
Protein present in plant vascular tissue (xylem and vascular cambium) is detected by anti-KLH antibodies (H glund et al. 2002) which might lead to false results in IL when using anti-peptide antibodies generated to KLH-conjugated peptide.
Heat-shock protein 70 (Hsp70) is the major stress-inducible protein in vertebrates and is highly conserved throughout evolution. It plays a role as a molecular chaperone and is important for allowing cells to cope with acute stressor insult, especially those affecting the protein machinery. Heat shock cognate protein 70 (HSC70), is a highly conserved protein and a member of the family of molecular chaperones.

<em>Helicobacter pylori</em> are spiral-shaped, gram-negative bacteria that inhabit the mucosal lining of the gastric epithelium. Infection with <em>H. pylori</em> is strongly associated with many gastroduodenal diseases, including intestinal-type carcinomas, peptic and gastric ulcers, and chronic gastritis. There is evidence linking these bacteria to gastric and mucosa-associated lymphoid tissue lymphomas, and <em>H. pylori</em> has also been indicated as a risk factor for colorectal polyps in children.
