Lab

Sandwich ELISA - Recombinant human IL-1 beta protein (Active) (AB259387)

Background subtracted standard curve using Human IL-1 beta Antibody Pair - BSA and Azide free (ab241807) and Recombinant human IL-1 beta protein (Active) (ab259387) in sandwich ELISA. The ELISA was performed using the components of the corresponding SimpleStep® kit, which uses the same antibody pair with a different formulation and format.

M + 1.02 Da (calc mass 17433.98)

The spectrum was recorded with a 6545XT AdvanceBio LC/Q-TOF (Agilent Technologies) and a MabPac RP column (42.1x50 mm, 4 μm, Thermo Scientific). 5 μL of purified protein was injected and the gradient run from 85 % water : FA (99.9 : 0.1 v/v) and 15 % acetonitrile : FA (90 : 9.9 : 0.1 v/v/v) to 55 % water : FA (99.9 : 0.1 v/v) and 45 % acetonitrile : FA (90 : 9.9 : 0.1 v/v/v) within 3 minutes followed by an isocratic step for another 2.5 min. Flow rate was 0.4 mL/min and the column compartment temperature was 60 °C. Data was analysed and deconvoluted using the Bioconfirm software (Agilent Technologies).

Sandwich ELISA - Recombinant human IL-1 beta protein (Active) (AB259387)

Human IL-6 concentration was interpolated from the IL-6 standard curve. Supernatants from cell culture samples were serially diluted and assessed by the Human IL-6 ELISA kit (ab178013). Wild-type and IL-6 knockout A549 cells (ab273751) were assessed in duplicate (n=2). Cells were either treated with 20 ng/mL active recombinant human IL-1 beta protein (ab259387) for 24 h to induce expression of IL-6 or not treated with IL-1 beta. Data are represented as the mean and error bars represent standard deviation.

Purity : 100%

The spectrum was recorded using a 1260 Infinity II HPLC system with DAD and a MabPac RP column (3.0x100 mm, 4 μm). 5 μL of purified protein was injected and the gradient run from 80 % water : TFA (99.9 : 0.1 v/v) and 20 % acetonitrile : water : TFA (90 : 9.9 : 0.1 v/v/v) to 20 % water : TFA (99.9 : 0.1 v/v) and 80 % acetonitrile : water : TFA (90 : 9.9 : 0.1 v/v/v) within 3 minutes followed by an isocratic step for another 3 min. Flow rate was 0.5 mL/min and the column compartment temperature was 50 °C.
