Source
Alexa Fluor 647-Labeled Human M-CSF R Protein, His Tag (CSR-HA2H4) is produced via conjugation of AF647 to Human M-CSF R, His Tag with a new generation site-specific technology under Star Staining labeling platform. Human M-CSF R, His Tag is expressed from human 293 cells (HEK293). It contains AA Ile 20 - Glu 512 (Accession # P07333).
Predicted N-terminus: Ile 20

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.
