What is the delivery time for catalogue peptides?
As a supplier of catalogue peptides, one of the most frequently asked questions by our customers is about the delivery time. In this blog post, I'll go into detail about the factors that influence the delivery time of catalogue peptides and provide general estimates to give you a better understanding.
Factors Affecting Delivery Time
Peptide Complexity
The complexity of the peptide sequence is a primary factor in determining delivery time. Simple peptides with short sequences and common amino acids are relatively easy to synthesize. Our production team can quickly assemble these peptides using standard chemical synthesis techniques. These straightforward peptides often have shorter lead - times, usually within 1 - 3 business days if they are in stock or can be synthesized rapidly.
On the other hand, complex peptides pose challenges. For example, peptides with unusual amino acids, such as non - natural amino acids, or those with complex post - translational modifications like phosphorylation or glycosylation require specialized reagents and techniques. The synthesis process for these complex peptides is more intricate and time - consuming. It may take up to 2 - 4 weeks to synthesize and purify a highly complex peptide to meet the required quality standards.
Quantity Ordered
The amount of the peptide you order also affects the delivery time. If you only need a small quantity of a common peptide from our catalogue, we might have it in stock, allowing for immediate dispatch. This can significantly reduce the delivery time to as short as 1 - 2 days, excluding shipping time.
However, larger quantities may require additional synthesis. The production process needs to be scaled up, which means more raw materials need to be used, and the synthesis and purification steps take longer. For bulk orders of peptides, the delivery time can range from 5 business days to several weeks, depending on the quantity and complexity of the peptide.
Availability of Raw Materials
The availability of raw materials is another crucial factor. Our production of peptides relies on various amino acids and reagents. If a particular amino acid or reagent is in short supply in the market, it can cause delays in the production process. We work closely with multiple suppliers to ensure a stable supply of raw materials. But in cases where there are global shortages or supply chain disruptions, the delivery time of the peptides can be extended.
Quality Control and Testing
Before shipping any peptide, we conduct rigorous quality control and testing. This includes methods such as high - performance liquid chromatography (HPLC) to determine the purity of the peptide and mass spectrometry to confirm its molecular weight. These tests are essential to ensure that the peptide meets the high - quality standards we promise to our customers.
The quality control process can take some time, especially for complex peptides. For simple peptides, the quality control may take 1 - 2 days, while for complex ones, it could take up to a week. Any issues detected during quality control will require re - work or additional purification steps, further delaying the delivery.
General Delivery Time Estimates
For our most common and simple catalogue peptides, if they are in stock, we can usually ship them within 1 - 2 business days. Once shipped, the transit time depends on the shipping method and the destination. For domestic orders within the same country, standard shipping may take 2 - 5 business days, while express shipping can reduce this to 1 - 2 days.
For international orders, the shipping time varies widely. Standard international shipping can take 7 - 14 business days, while express international shipping can deliver the peptides in 3 - 7 business days.
If the peptide needs to be synthesized, for simple peptides, we can typically complete the synthesis and quality control within 3 - 5 business days. After that, the shipping time is added as described above.
For complex peptides, the synthesis and purification process can take 2 - 4 weeks. Once the peptide passes the quality control tests, the shipping process follows, with the time depending on the shipping method and destination as mentioned earlier.
Examples of Our Catalogue Peptides
We have a wide range of catalogue peptides available. For instance, Formyl - LHRH (2 - 10) is a relatively simple peptide in our catalogue. If it is in stock, we can ship it out quickly, usually within 1 - 2 business days.
Another example is Prepro VIP (156 - 170) (human). Depending on its availability and complexity, the synthesis and delivery time may vary. If it needs to be synthesized, it may take around 3 - 5 business days for production and quality control, and then additional shipping time.
PTH (70 - 84) (human) is also one of our popular catalogue peptides. The delivery time for this peptide will be influenced by factors such as quantity, complexity, and raw material availability as discussed above.
How to Minimize Delivery Time
If you need the peptides urgently, here are some tips:
- Order in advance: If you know you will need the peptides for a future experiment, place your order as early as possible. This gives us sufficient time to synthesize and test the peptides without rushing the process.
- Choose in - stock peptides: Check our product list to see if the peptides you need are in stock. Ordering in - stock peptides can significantly reduce the delivery time.
- Communicate your requirements clearly: When placing an order, clearly state your quantity, quality requirements, and the desired delivery date. This helps us plan the production process more efficiently.
