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.

溶解建議
Sterile Filtered White lyophilized （freeze-dried） powder. Lyophilized from a concentrated （1mg/ml） solution containing no additives. It is recommended to reconstitute the lyophilized LALF in sterile 20mM acetic acid not less than 100ug/ml， which can then be further diluted to other aqueous solutions.
保存建議
Lyophilized LALF although stable at room temperature for 3 weeks， should be stored desiccated below -18℃. Upon reconstitution LALF should be stored at 4℃ between 2-7 days and for future use below
-18℃.
For long term storage it is recommended to add a carrier protein （0.1% HSA or BSA）.
Please prevent freeze-thaw cycles.
