Delivery and availability
All our un-conjugated antibodies are delivered as 100µg of purified antibody in 200µl buffer: 0.5 mg IgG/ml in Tris saline (20mM Tris pH7.3, 150mM NaCl), 0.02% sodium azide, with 0.5% bovine serum albumin.
No. The tiny amount of sodium azide (NaN3) present in our products ensures that they comply with the regulations for the excepted quantity exemptions of dangerous goods. See the MSDS.
Aliquot and store at -20°C, with minimal freeze/thawing. A working aliquot may be refrigerated at 4C for a few weeks and still remain viable.
All our goat antibodies are polyclonal and affinity-purified with the immunizing peptide. They are all IgG, and require Protein G and not Protein A, for purification.
Domesticated Nepalese goat, Capra hircus.
US origin, Bovine.
