Product Overview

Tag	N/A
Host Species	Human
Synonym	Complement C1q tumor necrosis factor-related protein 2, CTRP2, zacrp2.
Background	C1QTNF2 can be found in many different organism parts such as the testis, cervix. C1QTNF2 is located in the extracellular space and has various roles such as activation of MAPK activity, positive regulation of fatty acid oxidation, positive regulation of glycogen biosynthetic process, and positive regulation of glucose import.
Description	C1QTNF2 Protein is a 29,640 Da protein containing 280 a.a. fused to a 10 a.a. N-Terminal His-tag.
Source	E. coli

Endotoxin	<1.0 EU per μg by the LAL method.
Formulation	C1QTNF2 Human was filtered (0.4µm) and lyophilized from 0.5 mg/ml supplied in 0.03M Acetate buffer, pH 4.
Stability	Recombinant protein is stable for 12 months at -70°C
Usage	For Research Use Only
Storage	Store lyophilized C1QTNF2 uman at -20°C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted C1QTNF2 an be stored at 4°C for a limited period of time; it does not show any change after two weeks at 4°C.

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.
