Other Tags and Version Biotin & Other Labeled Version
This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag. This protein undergoes autocatalytic cleavage to release the pro-peptide and mature chain. The protein has a calculated MW of 13.9 kDa and 61.1 kDa. The protein migrates as 16 kDa and 66 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Labeling
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Protein Ratio
Passed as determined by the SABA assay / HABA assay / binding ELISA.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

FAQ
- product
Can lyophilized proteins remain stable during room-temperature shipping or temporary room-temperature exposure?
In general, lyophilized proteins remain stable during room-temperature shipping or temporary exposure to room-temperature conditions.
Many ACROBiosystems recombinant proteins are supplied in lyophilized (freeze-dried) form. The lyophilization process effectively removes moisture from the product, helping reduce degradation-related reactions and improve protein stability during transportation and storage.
To evaluate the stability of lyophilized proteins under normal temperature conditions, ACROBiosystems conducted a stability study on 11 representative lyophilized protein products at 37°C. The study demonstrated that these proteins maintained good quality stability after storage at 37°C for approximately 20 days. Based on these validation results, temporary room-temperature exposure during shipping or handling is generally not expected to have a significant impact on product quality or downstream application performance.
To ensure optimal long-term stability, products should be stored according to the storage conditions specified in the product Certificate of Analysis (COA) upon receipt.

What key experimental conditions should be considered for PCSK9–LDLR binding assays?
It is recommended to perform PCSK9–LDLR binding assays under acidic conditions, as the interaction exhibits higher activity in acidic environments compared to neutral ones. Reference: Effects of pH and Low Density Lipoprotein (LDL) on PCSK9-dependent LDL Receptor Regulation.
