Product Overview

Tag N/A
Host Species Human
Synonym BCL2/Adenovirus E1B 19kDa Interacting Protein 1, NIP1, BCL2/AdenovirusE1B 19 KDa Protein-Interacting Protein 1, Transformation-Related Gene 8Protein, TRG-8, BCL2/Adenovirus E1B 19kD-Interacting Protein 1, VesicleTransport Protein SEC20, SEC20L, SEC20, Vesicle transport protein SEC20.
Background BNIP1 belongs to the of the BCL2/adenovirus E1B 19 kd-interactingprotein (BNIP) family. BNIP1 interacts with the E1B 19 kDa protein, which defendscells from virally-induced cell death. In addition, BNIP1 interacts with E1B 19kDa-like sequences of BCL2 which is an additional apoptotic protector. Addingup, BNIP1 is implicated in vesicle transport into the endoplasmic reticulum.Alternative splicing results of BNIP1 in four protein products with identicalN- and C-termini have been found.
Description BNIP1 Human Recombinant expressed in E.Coli is a single, non-glycosylatedpolypeptide chain containing 222a.a. (1-199 a.a) and having a molecularmass of 25.2kDa.BNIP1 is fused to a 23a.a. His-tag at N-terminusand purified by unique purification methods.
Source E.coli

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.
