Product Overview
TGFBI,also named as BIGH3,Kerato-epithelin and RGD-CAP,binds to type I,II,and IV collagens. TGFBI is an adhesion protein which may play an important role in cell-collagen interactions. In cartilage,it may be involved in endochondral bone formation. TGFBI is an extracellular matrix adaptor protein,it has been reported to be differentially expressed in transformed tissues. TGFBI is a predictive factor of the response to chemotherapy,and suggest the use of TGFBI-derived peptides as possible therapeutic adjuvants for the enhancement of responses to chemotherapy. Defects in TGFBI are the cause of epithelial basement membrane corneal dystrophy (EBMD). Defects in TGFBI are the cause of corneal dystrophy Groenouw type 1 (CDGG1). Defects in TGFBI are the cause of corneal dystrophy lattice type 1 (CDL1). Defects in TGFBI are a cause of corneal dystrophy Thiel-Behnke type (CDTB). Defects in TGFBI are the cause of Reis-Buecklers corneal dystrophy (CDRB). Defects in TGFBI are the cause of lattice corneal dystrophy type 3A (CDL3A). Defects in TGFBI are the cause of Avellino corneal dystrophy (ACD).

The recommended starting dilution for Western Blot is WB 1:500-1:2000;IHC 1:50-1:200. Optimal dilution should be determined empirically for each laboratory setup, sample type, and detection system. Use freshly prepared lysates with protease inhibitors; add phosphatase inhibitors if studying phosphorylation-dependent forms of TGFBI. Expected band size: Calculated 75 kDa, Observed Refer to figures. If background is high, increase blocking (5% non-fat milk or BSA in TBST) and/or increase wash stringency.
For IHC-P, heat-induced epitope retrieval (HIER) is typically required. Recommended starting conditions: citrate buffer pH 6.0 (microwave or pressure cooker, ~20 min) for rodent samples; EDTA buffer pH 9.0 for human clinical samples. After retrieval, allow sections to cool gradually before proceeding to blocking. Include a TGFBI-positive tissue control (confirmed by literature or database expression data) and a negative isotype control in every run. Recommended dilution: WB 1:500-1:2000;IHC 1:50-1:200. Refer to the product datasheet for any target-specific retrieval guidance.
This antibody has been experimentally validated in: Human, Mouse, Rat. Cross-reactivity with other species has not been systematically evaluated. If your sample species is not listed, assess immunogen sequence homology to your target species ortholog. The immunogen used is: "Fusion protein of human TGFBI" — higher sequence identity between species increases the probability of cross-reactivity, but experimental validation with appropriate controls is necessary before drawing scientific conclusions.
Store at -20℃ Valid for 12 months. Avoid freeze / thaw cycles. Storage Buffer: PBS with 0.05% NaN3 and 40% Glycerol,pH7.4. To maintain antibody activity, avoid repeated freeze-thaw cycles. Aliquot into single-use volumes before first freeze. If working with the antibody frequently, keep a working stock at 4°C for up to 4 weeks — add 0.02% sodium azide to the working stock as a bacteriostatic agent if azide is not already present in the buffer. Monitor performance against a validated positive control when transitioning between storage aliquots or lots.
Polyclonal antibodies are produced from immunized animals and may exhibit some degree of lot-to-lot variation in titer, background, and sensitivity. Each production lot is tested for performance against established acceptance criteria. When transitioning to a new lot, run a side-by-side pilot comparison against your previous lot using a validated positive control sample before updating your standard protocol. If significant performance differences are observed, contact our technical support team — titer adjustments may resolve the issue in most cases.
