Product Overview

Description	Recombinant Human CCL5 Protein is expressed from E.coli with His-SUMO tag at the N-Terminus.It contains Ser24-Ser91.
Purity	> 95% as determined by Tris-Bis PAGE
Accession	P13501
Target Symbol	CCL5
Synonyms	MuRantes; SIS-delta; Scya5; Ccl5; D17S136E; eoCP; RANTES; SCYA5; SISd; TCP228; CCL5
Species	Human
Expression System	E. coli
Tag	N-His,SUMO
Expression Range	Ser24-Ser91
Mol. Weight	The protein has a predicted MW of 21 kDa. Due to the protein can cleaved into two chains, so it migrates to 15-18 kDa and 22-25 kDa based on Tris-Bis PAGE result.
Form	Lyophilized
Formulation	Lyophilized from 0.22um filtered solution in 20mM Tris,0.3M NaCl (pH 8.5). Normally 8% trehalose is added as protectant before lyophilization.
Endotoxin	Less than 1EU per ug by the LAL method.
Activity	Immobilized Human CCL5, His Tag at 0.5ug/ml (100ul/well) on the plate. Dose response curve for Anti-CCL5 Antibody, hFc Tag with the EC50 of 4.4ng/ml determined by ELISA (QC Test). Contact us for detailed testing images.
Storage	Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
Shipping	Shipped at ambient temperature.
Gene Background	The CCR5 and the CCL5 ligand have been detected in some hematological malignancies, lymphomas, and a great number of solid tumors, but extensive studies on the role of the CCL5/CCR axis were performed only in a limited number of cancers.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
