No, it is caused by an over conjugated condition.
The normal pH tolerance is 6.5~8.5. The quality of the product will be damaged if pH value is outside of this range.
With the packaging supplied by Flogen and storage at 2~8℃ away from light, the shelf life is 3 years.
When the temperature is below 37℃ with the package and solution supplied by Flogen, the quality of phycobiliprotein product can be highly stable or even unchanged for several days. However, when the temperature reaches above 37℃, phycobiliprotein will denature easily within a short period of time.

Lyophilized Phycobiliprotein

l. Ready-to-use: It is ready to use without any pre-treatment steps, such as buffer exchange, concentration adjustment, quality checks, etc. In addition, because lyophilization process does not include any material that affects conjugation, there’s no need to worry about the quality of conjugates which, on the other hand, will be affected if there is an incomplete elimination of ammonium sulfate in the ammonium sulfate solution form. 2. Stability: Higher stability, longer shelf life, and also much easier to transport. 3. Flexible production capacity:Available in small and large quantity production 4. Quality: The quality of lyophilized phycobiliproteins is the same as phycobiliproteins in saturated ammonium sulfate solution; their purity and fluorescence performance are the same. 5. Economical effectiveness: Decrease cost in packing and transportation due to much smaller size of the product; reduced labor cost, time consumed, and sample wasted during protein purification in ammonium sulfate solution. 6. Reproducibility: Reducing deviation between experiments, increasing batch-to-batch consistency.
Our R&D team has gone through numerous experiments and validations, and has developed the lyophilization process without altering the fluorescent intensity and light absorbance property of phycobiliproteins. Moreover, Lyo Flogen® has passed strict quality tests to ensure it possesses the quality of phycobiliproteins stored in saturated ammonium sulfate solution.
Does the lyophilized phycobiliprotein follow the same conjugation procedures as the Phycobiliprotein products store in ammonium sulfate solution?
Because there are no preservatives in lyophilized phycobiliprotein and the package is not sterilized, to preserve our product from other microorganisms or enzymes, or to maintain its original property, we do not recommend long term storage of re-suspended lyophilized phycobiliprotein or freezing and thawing upon usage. We suggest you to re-suspend it in concentration greater than 10mg/ml, stored it in 2~8℃ and use the product within a week.
No ammonium sulfate or other material that will interfere with the conjugation process is added in this product.

Recombinant Protein

Please follow the instruction to reconstitute the products. If the product is sterile, please follow the operation procedure for sterile product. If not specifically prohibited or the system is allowed, you may add 0.09% NaN3 to inhibit bacterial growth for longer shelf life.
Storage and method of reconstitution vary for different products. Please follow the instruction in the package to store the lyophilized product in 2~8 ℃ or -20 ℃. Please follow the instruction to reconstitute the products. If you are unable use all the product at once, we recommend you to aliquot the product into smaller portions for each single usage and store them in -80℃ to avoid freeze and thaw.
If it states “sterilized” in the instruction, we recommend you to store and operate under sterilized conditions.
The shelf life varies. Please refer to the label or instruction in you package. We can guarantee the valid period of our recombinant protein products is at least one year from the date you receive the product.
