Frequently Asked Questions
A: Yes, our technical support team is available to discuss your project with you. Please contact us here.
A: Antibodies can be shipped according to the vendor’s instructions to:
AlphaThera Inc.
3401 Grays Ferry Ave
Pennovation Lab Building 250

A: For most subclasses and species of antibody, oYo-Link will result in the conjugation of ~2 labels per antibody; one per heavy chain. For example, ~95% of human IgG and Rabbit IgG will have two labels per antibody. However, there are a few antibodies, such as mouse IgG2b and goat IgG, which may result in slightly less efficient conjugation. In this case, 60 to 80% of the antibody will be labeled with 1 or 2 labels per antibody. View our antibody conjugation efficiency table herefor more information.
A: For the 1st antibody, the fee is $75 plus the cost of reagents. FPLC purification is available for $250 per conjugate.
A: For oligonucleotides, we can provide labeling between 25ug to 3mg of antibody. For conjugation of all other cargos, we can offer labeling between 100ug to 3mg of antibody. If you require labeling of cargos (with the exception of oligo) to antibody quantities below 100ug, this will be charged at the rate of labeling 100ug.
A: Antibody samples as dilute as 50 ug/mL are accepted.
A: Purification of conjugates is available for an additional fee, which will be provided upon request. Two types of purification are available: 1. Purification using oYo-Capture Magnetic Beads 2. Size exclusion chromatography; this requires a minimum of 100 ug of antibody.
A: Upon receipt of your antibody, conjugation and shipping of your conjugates will take 2-3 days. Lead time for oligonucleotide conjugation is 2-3 days (for conjugation without purification) from when we receive the oligo/s from IDT or Genscript.
A: The QC data for antibody conjugation will be provided as an SDS-PAGE Gel of unconjugated and conjugated antibody. Additional QC data can be provided upon request.
