CD5 Antigen-Like (CD5L) is a soluble protein that belongs to group B of the scavenger receptor cysteine-rich (SRCR) superfamily and contains three SRCR domains. CD5L is a secreted glycoprotein and expressed by macrophages presentin lymphoid tissues. It binds to myelomonocytic and lymphoid cells and may play an important role in the regulation of the innate and adaptive immune systems. CD5L functions as a pattern recognition molecule by binding both lipoteichoic acid (LTA) on Gram positive and lipopolysaccharide (LPS) on Gram-negative bacteria and the SRCR domain one of CD5L retains both the LPS and LTA binding activities. Furthermore, CD5L seems to play a role as an inhibitor of apoptosis.
Description
Recombinant Human CD5 Antigen-Like is produced by our Mammalian expression system and the target gene encoding Ser20-Gly347 is expressed with a 6His tag at the C-terminus.
Molecular Weight
37.09 KDa
Accession Number
O43866
Endotoxin Level
Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.
Notes
Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100ug/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Shipping
The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.
