||CD40L is the ligand for CD40, a member of the tumour necrosis factor (TNF) receptor superfamily. CD40L is expressed mainly on activated CD4+ T-lymphocytes as a single-pass type II membrane protein. Proteolytic processing of the membrane form results in a soluble secreted form of CD40L. Microglia and astrocytes interact via CD40 receptor and CD40 ligand.

||A synthetic peptide (HRRLDKIEDERNLHEDFVF) corresponding to amino acid sequence 47-65 from the N-terminus of human CD40L.
||CD40-L; TRAP; gp39; TRAM; CD154; Tumour necrosis factor ligand superfamily member 5; TNFSF5; CD40L;
||P29965 CD40L_HUMAN; P27548 CD40L_MOUSE
||Affinity purified on antigen column
||Immunohistochemistry (IHC) and Western Blotting (WB). A concentration of 0.1-0.5 ug/mL is recommended for WB. Human CD40L has a predicted length of 261 residues and MW of 29 kDa. The observed size is 32 kDa. A concentration of 0.5-1.0 ug/mL is recommended to detect CD40L in formalin fixed and paraffin embedded tissues. Heat mediated antigen retrieval is required. Boiling the paraffin sections in 10mM citrate buffer, pH 6.0 for 20 minutes is recommended. Biosensis recommends optimal dilutions/concentrations should be determined by the end user.
||The specificity of this antibody has been confirmed by WB and IHC against the antigen.
||If you wish to use this product in a species other than those specified here and want to determine the amino acid sequence homology between the immunogen and the corresponding protein in that species, simply copy the amino acid sequence for this immunogen and test it on the BLAST database that you can access through the link below. Please note that antibodies raised against synthetic peptides are quite often very specific for that peptide. What this means in practise is that a single amino acid difference may be enough to restrict the specificity to a particular molecule.
The BLAST database can also be used to compare any amino acid sequence between species and between protein. The full amino acid sequence of the target protein can be found by following the link in the Accession field. You can then search any amino acid sequence in the target protein using the BLAST database. When selecting a sequence to search, please chose carefully, as the sequence you chose may be a precursor rather than the mature protein for example.
||Lyophilised with 5mg BSA, 0.9mg NaCl, 0.2mg Na2HPO4, 0.05mg Thimerosal, 0.05mg NaN3
||Reconstitute in 100 uL of sterile distilled water to achieve an antibody concentration of 1 mg/mL. Centrifuge to remove any insoluble material.
||After reconstitution, aliquot and store at -20C for a higher stability. Avoid freeze-thaw cycles.
