Derivatization with these agents has the effect of reversing the charge of the lysinyl residues. In one embodiment of the foregoing the cleavage sequence comprises the sequence RX or KX, wherein X is any L-amino acid other than proline. Of particular interest are the hydrophilic amino acids aspartate, glutamate, and serine, and glycine. Contaminant components of its natural environment are materials that would typically interfere with diagnostic or therapeutic uses for the polypeptide, and may include enzymes, hormones, and other proteinaceous or non-proteinaceous solutes. In another embodiment of the dimeric XTEN conjugate, the first b the second XTEN each comprises one or more cysteine residues, and further comprises a first cross-linker conjugated to each cysteine residue of the first XTEN and a second cross-linker conjugated to each cysteine residue of the second XTEN, wherein the first and the second cross- linkers are independently selected from the group consisting of the cross-linkers set forth in Table To make the XTEN-folate, the modified aldehyde-XTEN is mixed with a payload with a dps amino-group and a mild reducing agent such as mM sodium cyanoborohydride.

Akinorr Maleimides do not react with tyrosines, histidines or methionines. Description: 4 digit 16 segment Alpha-numeric display with 1 inch digits In the 1 inch versions of these displays use two LEDs for some of the segments the longer ones.

In one embodiment, XTEN sequences have predominately four to six types of amino acids selected from glycine Hhwalanine Aserine Sthreonine Tglutamate E or proline P that are arranged in a substantially non-repetitive sequence that is about 36 to aboutor about to aboutor about to about amino acid residues in length.

Such agents may include peptides, proteins, carbohydrates, nucleic acids, nucleosides, oligonucleotides, and small molecule synthetic compounds, or analogs thereof. In one embodiment, the pharmaceutical composition comprises the binding fusion protein and at least one pharmaceutically acceptable carrier. In another embodiment, the sdp. In some embodiments, the invention provides compositions of any of the XTEN described herein that is covalently linked to one or more molecules of at least a first cross-linker, wherein the cross-linker is selected from, the group con sisting of the cross-linkers set forth in Table 13, the alkyne ddp set forth in Table 15, and the azide reaetants set forth in Table The administration of polypeptides comprising XTEN, using conventional therapeutic practices and dosing, would generally not result in the formation of neutralizing antibodies to the XTEN sequence, and also reduce the immunogenicity of the payload in the conjugates.

For an ADC to be effective and relatively nontoxic, the chemotherapeutic drug should remain in stable linkage with the mAb while in circulation but should be efficiently released on. The heteroatom of the nucleophilic group of a lysine- or cysteine-engineered XTEN is reactive to an electrophilic group on a cross-linker and forms a covalent bond to the cross-linker unit, resulting in an XTEN-cross-linker conjugate.

In embodiments wherein the XTEN-cross-linker is conjugated to a payload, the sulfhydryl-containing payload and the XTEN-cross-linker conjugate are mixed in a molar ratio corresponding ds; that desired for the final conjugate taking into account the number vsp expected cross-linkers conjugated to one or more amino groups per molecule of the XTEN and consistent with the single sulfhydryl group that exists on the pay load.

Folate receptor can be overexpressed by a number of tumors including ovarian, breast, renal, lung, colorectal, and brain. Examples of cysteine island are shown in Table 5.

Self-immolative dendrimers as novel drug delivery platforms. A heterobifunctional reagent is reacted with a first protein using the more labile group. It is an object of the present invention to provide such engineered XTEN polypeptides for use in creating conjugates with payload agents of interest as compositions with enhanced pharmaceutical properties, including c4 pharmacokinetic properties. Preferred nucleophiles include thiol, thiolate, and primary amine. DM1 has been also coupled to Millennium.

WOA2 — Xten conjugate compositions and methods of making same — Google Patents In one embodiment, the amine-containing protein is dap in conjugation buffer of, e. Thus, there remains a need to overcome this unspecific nature of many chemotherapeutics so that efficacy can be increased and side effects and tolerance in the patient can be reduced.

EGS Ethylene glycol Z? This lighting system was designed by John V Teeces to be a simple, customizable, expandable and affordable solution for dome lighting. In another embodiment of the conjugate of formula XI, C 2 is the reaction product of a first and a second click chemistry reactant selected from Table Histidyl side chains and amino groups react in the unprotonated form with iodoacetyl groups above pH 5 and pH 7, respectively. Refine more Format Format. In some cases, the ratio may be somewhat lower, however, such as up to aboutor In one embodiment, the invention provides dimeric conjugates containing two different payload molecules linked separately to two cysteine- engineered XTEN backbones, as illustrated in FIG.

Deletion variants, therefore, include all fragments of a payload polypeptide sequence. An intermediate is produced by reacting XTEN with a trifunctional linker comprising two azide functions and an NHS function followed by the addition of payload A to the thiol group wh maleimide chemistry the order of b two steps can be inverted.

Pyridyl disulfides react with sulfhydryl groups over a broad pH range the optimal pH is to form disulfide bonds linking XTEN to payloads. Dp in denatured conformation have, for example, characteristic circular dichroism CD spectra and are characterized by a lack of long-range interactions as determined by NMR. Keeping the numbers array in ascending order, with 0 at the beginning rather than after 9, makes it really simple to get numbers generated by our program onto the display see example program 2.

The most important is the dap that since the outputs of a digital chip can only be More information. In some embodiments, the XTEN utilized to create the subject conjugates comprise XTEN selected from any one of the sequences in Table 2, Table 3, and Tableswhich may be linked to the payload component directly or via cross-linkers disclosed herein. The polymer may be linear or branched, it may comprise modified amino acids, and it may be interrupted by non-amino acids. It has been difficult to obtain a homogeneous preparation of full-length XTENs due to one or more of the above-mentioned reasons.

Several factors can contribute to the low immunogenicity of XTEN, e. In one embodiment of the foregoing the cleavage sequence comprises the sequence RX or KX, wherein X is any L-amino acid other than proline.

Digital Trainer Kit More information. However, it may be necessary to first convert the staggered ends commonly produced after endonuclease digestion to blunt ends to make them compatible for ligation. In one embodiment of the trimeric XTEN -payload conjugate composition, the first payload is a targeting moiety with specific binding affinity to a target, wherein the targeting moiety is selected from the group consisting of the targeting moieties set forth in Tables and 21and the second and the third payloads are a drug, which may be the same or may be different and wherein the drug is selected from the group consisting of the drugs set forth in Table 1 1Table 18, and Table In some cases, the XTEN can contain aboutor aboutor about glutamic residues per 20kDa of XTEN that can result in an XTEN with charged residues that would have very similar pKa, which can increase the charge homogeneity of the product and sharpen its isoelectric point, enhance the physicochemical properties of the resulting XTEN conjugate, and hence, simplifying purification procedures.
