General notes
ab221960 is the carrier-free version of ab150407.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free production
Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.
Our Low endotoxin, azide-free formats have low endotoxin level (≤ 1 EU/ml, determined by the LAL assay) and are free from azide, to achieve consistent experimental results in functional assays.

Relevance
Estriol is a hydroxylated metabolite of ESTRADIOL or ESTRONE that has a hydroxyl group at C3-beta, 16-alpha, and 17-beta position. Estriol is the main estrogen in the blood and urine of pregnant females. During pregnancy, large amount of estriol is produced by the placenta. Serum estriol determinations reflect the status of the fetus and are used to evaluate fetal distress and placental function. Estriol increases until term, reaches a plateau at the 40th week of gestation and then declines. Isomers with inversion of the hydroxyl group or groups are called epiestriol. It is used in the treatment of osteoporosis in combination with Vitamin D. Its expression also seems to be one of the direct causes of preterm labour, together with cervical ultrasound mesurements and espression of Foetal Fibronectin. -

This ELISA data was generated with the same anti-Estriol antibody clone [EPPTXR3] in a different buffer formulation (cat# ab150407).
2 ug/ml of goat anti-rabbit IgG was coated into 96-wells. After blocking with 1%BSA, serial dilution of Estriol (0, 0.1, 0.5, 2, 5, 10, 20, and 50ng/ml) were added together with HRP conjugated Estriol (1/100) and 0.075 ug/ml of ab150407 into 96-wells. After washing, TMB substrate was used to develop the color.

2 ug/ml of goat anti-rabbit IgG was coated into 96-wells. After blocking with 1% BSA, 20ng/ml of various buffer containing Estriol, Estradiol, Estrone, 16-Epiestriol, Estriol 3-sulfate, 16-Hydroxyestrone , or PBS buffer only were added together with HRP conjugated Estriol (1/100) and 0.075 ug/ml of ab150407 into 96- wells. After washing, TMB substrate was used to develop the color.
