PrecipHen® Immunoprecipitation Reagent

Our PrecipHen® is made from goat anti-chicken IgY antibodies covalently attached to agarose beads. It is designed for use with chicken antibodies in immunoprecipitation (IP), chromatin immunoprecipitation (ChIP), and protein purification applications.

Notes

Immune sera was collected from goats that were hyper-immunized with purified chicken IgY. Goat anti-chicken IgY antibodies were affinity purified from the sera over a chicken IgY column, and then conjugated to N-hydroxysuccinimide (NHS) -activated agarose beads. After blocking residual NHS sites, the agarose beads were washed exhaustively with 50 mM HEPES buffer (pH 7.6) with 5 mM EDTA (“TE buffer”) . Sodium azide was then added to a final concentration of 0.02% (w/v) .

Specificity

H&L; does not cross-react with mammalian IgGs.

Quality Control

The capacity of PrecipHen® was determined by measuring the 2.5 mLs of PrecipHen. One milliliter aliquots of chicken IgY (200 μg/mL in TE buffer) were applied to the column and fractions were collected. A similar column of agarose (non-NHS activated) was used for comprison. The concentration of IgY passing through each column was measured, and the total amount of IgY that bound to the column was calculated.
