Recombinant Human Complement Factor H-related Protein 4 is produced by our Mammalian expression system and the target gene encoding Glu20-Glu578 is expressed with a 6His tag at the C-terminus.
Alternative Names
Complement factor H-related protein 4; FHR-4; CFHR4; CFHL4
Background
Complement factor H-related protein 4 is a protein that in humans is encoded by the CFHR4 gene. It is a secreted protein that belongs to the complement factor H protein family. Members of the H-related protein family are exclusively composed of individually folded protein domains. CFHR4 is synthesized as a 578 amino acid precursor that contains an 19 amino acid signal peptide and a 569 amino acid mature chain. Human CFHR4 is involved in complement regulation. It can associate with lipoproteins and may play a role in lipid metabolism.

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.
