What is the antibody's immunogen sequence?
A lot of time and money has been put into selecting immunogen sequences. We have decided to protect this information by not publishing it on our website. However, some of these sequences may be made available on request.
What is the antibody shelf-life?
Unless otherwise specified, St John's Laboratory antibodies have a 1-year shelf life from the time of dispatched. Please store each antibody according to the specifications on the product sheet upon receipt.
What is the antibody concentration?
Concentrations vary across the St John's Laboratory product range. Please refer to the product sheet for details.
Is it possible to get the antibody with custom formulation?
We are able to remove glycerol, sodium azide or BSA from a selection of our antibodies with a minimum 1mg bulk purchase. Please submit your request to firstname.lastname@example.org, or alternatively call +44 (0) 208 223 3081 and we will assist your query as best as possible.
Do you offer custom antibody production services?
Not for custom antibody design, however, we can carry out conjugation of bulk antibody quantities for a selection of our products. If you are interested to receive bulk production please email email@example.com
Which antibody host species will show the best results?
Choose your antibodies according to the combination of primary and secondary antibody you will need. As a general rule, choosing a secondary antibody which targets the same species as that of the primary antibody host would be favourable. Eg. The primary antibody is produced in mice, so the secondary antibody will be anti-mouse.

Is tax charged on my order?
Our prices are exclusive of VAT (Value Added Tax) and VAT only applies to customers in the United Kingdom (UK). When placing an order through our online store VAT can be added during the checkout process if you are a UK business and normally pay VAT.
For UK customers, most academic institutions in the UK are qualified for zero rate VAT (commonly referred to as VAT exemption). If this applies to you, please provide us your VAT exemption certificate. We will add 20% VAT to your invoice if no certificate is received or if your institution does not have VAT exemption.
No tax is added to your purchase if you are a customer from outside of the EU. However, the customs office in your country may impose tax and duties on your order. Please provide us with your tax number at checkout as it will help to facilitate the customs clearance process.
If you are an EU customer outside of the UK, and if you provide us with your VAT/MwSt number (e.g. DE 111222333) please include the country code prefix for the VAT/MwSt number. You can obtain this number from the purchasing department of your institution. If you do not provide a valid VAT/MwSt number, we may need to charge you VAT/MwSt.
