Background

LALF has been isolated from the membranes of amebocytes of Limulus polyphemus. LALF is a single-chain polypeptide with a molecular weight of 11,800.
The principal structure of the molecule consists of 102 amino acids and is partially homologous with structures of molecules in the lactalbumin-lysozyme family.
LALF has a high affinity binding for LPS and bactericidal for gram negative bacteria.
LALF binds the lipid A part of a variety of chemically diverse LPSs.
It can be used for endotoxin removal and detection. LALF reacts with specific antisera in ELISA and Western blots.

Storage Prior to reconstitution store at 2-8°C. 
Following reconstitution store undiluted at 2-8°C for one week or (in aliquots) at -20°C for longer. 
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). 
Avoid repeated freezing and thawing.
Shelf life: one year from despatch.
