LifeTein Referral Rewards Program

Refer a colleague. Strengthen your research network. Get rewarded.

At LifeTein, many of our strongest collaborations begin with referrals from trusted scientists like you. To thank you for your support, we offer a simple and rewarding way to share our peptide and antibody services with your colleagues.

How it works: 1. Submit your referral using the form below 2. Your colleague receives 10% off their first order 3. Once their first order is completed, you receive your reward:

$25 Starbucks Gift Card

$25 Amazon Gift Card

OR $30 credit toward your next LifeTein order

*Offer valid for new customers only. Discount applies to the first order.

After submitting the form, feel free to introduce LifeTein directly to your colleague. Our team will ensure a smooth onboarding experience with responsive communication, high-quality synthesis, and reliable delivery.

Your reward will be issued after your colleague’s first order is successfully completed. Please allow 2–3 weeks for processing and delivery. If you have not received your reward within this timeframe, please contact us at [email protected].

Protein-Protein Interaction Studies

In FRET-based assays, TAMRA acts as an acceptor dye paired with donors like fluorescein. This configuration allows detection of molecular interactions between labeled peptides and target proteins. For instance, TAMRA-labeled kinase substrate peptides can reveal enzymatic activity by quantifying changes in FRET efficiency upon phosphorylation. Find other fluorescent pairs here.

How-to reference

How to solubilize my synthetic peptides? #

Please refer to this FAQ for details: Handling and Storage of Synthetic Peptides. If the peptides are still cloudy, or turbid, you may have reached the limit of solubility. When the peptides are insoluble in the buffer, please try to sonicate, centrifuge, and lyophilize the peptide. Make sure to break the lyophilized lumps into a fine powder. Then try a small volume of a good agent 8M Urea, NMP, DMF, or DMSO to dissolve the peptide. Then dilute with water or your desired buffer. For peptides with Arg or LYs, you should try to lower the pH to 6 because the protonated amino acids will help solubility. Sonication and the following solvents may help with difficult peptides: 1) Begin with 100 % acetonitrile then dilute with water until 50% 2) Begin with 100% DMSO then dilute with water until 30 % 3) Dissolve it with 8M Urea 4) Dissolve it with 6 or 8 M Guanidine hydrochloride 5) 6M GuHCL, 0.05% TFA, pH2, 6) 100% TFA 7) 40% AcOH, 30%ACN, 30% water

Storage reference

How stable are Rhodamine B conjugates during storage?

Conjugates are stable at -20°C for months when protected from light. Lyophilization is recommended for long-term storage, albeit with potential aggregation risks upon reconstitution.
