product information

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.


Purified keyhole limpet hemocyanin (KLH), whole molecule,

Host Rabbit
Clonality Polyclonal
Purity Affinity purified serum
Quantity 50 ĩg
Reconstitution For reconstitution please add 50 ĩl of dest. water

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

Tested applications Western blot (WB), ELISA (ELISA), immunolocalization (IL)

Additional information

protein present in plant vascular tissue (xylem and vascular cambium) is detected by anti-KLH antibodies (Höglund et al. 2002) which might lead to false results in IL when using anti-peptide antibodies generated to KLH-conjugated peptide. Further information about it can be found here.

50 µg of anti-KLH antibody is enough for ca. 50 western blots

Additional information

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.
