Product Overview

Description	Recombinant Cynomolgus IL-23 alpha&IL-12 beta Protein is expressed from HEK293 with His tag at the N-terminus of IL-23 alpha.It contains Val22-Pro189(IL-23 alpha) and Ile23-Ser328(IL-12 beta).
Gene Background	The interleukin (IL)-12 family of cytokines, including IL12 and IL 23, play an important role in driving aberrant Th1 and Th17 immune responses in patients with Crohn's disease (CD). Targeting this pathway has opened new avenues for therapeutic intervention. The balance of proinflammatory cytokines interleukin (IL)-12 and IL-23 plays a key role in shaping the development of antitumor or protumor immunity.
Accession	G7PIH8(IL-23 alpha)&XP_045250400.1(IL-12 beta)
Target Symbol	IL-23 alpha&IL-12 beta
Synonyms	IL23 alpha; IL12 beta; IL23 alpha&IL12 beta ; IL12 β; IL23 alpha&IL12 β
Species	Cynomolgus
Expression System	Mammalian Cell
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Tag	N-His
Expression Range	Val22-Pro189(IL-23 alpha) & Ile23-Ser328(IL-12 beta)
Mol. Weight	The protein has a predicted MW of 19.52 kDa (IL-23 alpha) and 34.76 kDa (IL-12 beta). Due to glycosylation, the protein migrates to 20-25 kDa (IL-23 alpha) and 40-50 kDa (IL-12 beta) based on Bis-Tris PAGE result.
Form	Lyophilized
Formulation	Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Endotoxin	Less than 1 EU per ug by the LAL method.
Activity	Immobilized Cynomolgus IL-23 alpha&IL-12 beta, His Tag at 5ug/ml (100ul/well) on the plate. Dose response curve for Human IL-23R, hFc Tag with the EC50 of 0.17ug/ml determined by ELISA (QC Test). The affinity constant of 4.05 nM as determined in SPR assay (Biacore T200).
Biotinylated	No
Shipping	Shipped at ambient temperature.
Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Reconstitution	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.

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.
